Data visualization refers to the techniques used to communicate data or information by encoding it as visual objects (e.g., points, lines or bars) contained in graphics. The goal is to communicate information clearly and efficiently to users. It is one of the steps in data analysis or data science. According to Vitaly Friedman (2008) the "main goal of data visualization is to communicate information clearly and effectively through graphical means. It doesn't mean that data visualization needs to look boring to be functional or extremely sophisticated to look beautiful. To convey ideas effectively, both aesthetic form and functionality need to go hand in hand, providing insights into a rather sparse and complex data set by communicating its key-aspects in a more intuitive way. Yet designers often fail to achieve a balance between form and function, creating gorgeous data visualizations which fail to serve their main purpose — to communicate information". Almost all data visualizations are created for human consumption. Knowledge of human perception and cognition is necessary when designing intuitive visualizations. Cognition refers to processes in human beings like perception, attention, learning, memory, thought, concept formation, reading, and problem solving. Human visual processing is efficient in detecting changes and making comparisons between quantities, sizes, shapes and variations in lightness. When properties of symbolic data are mapped to visual properties, humans can browse through large amounts of data efficiently. It is estimated that 2/3 of the brain's neurons can be involved in visual processing. Proper visualization provides a different approach to show potential connections, relationships, etc. which are not as obvious in non-visualized quantitative data. Visualization can become a means of data exploration. Database schema visualization is an essential process during the initial project design phase. Also, it can be useful when you need to reverse engineer a big schema and need to understand the various relationships between different tables. Below are given various database diagramming and visualization tools that will help you make sense of your complex [
MySQL Workbench simplifies database design and maintenance, automates time-consuming and error-prone tasks, and improves communication among DBA and developer teams. It enables data architects to visualize requirements, communicate with stakeholders, and resolve design issues before a major investment of time and resources is made There are different approaches on the scope of data visualization. One common focus is on information presentation, such as Friedman (2008). Friendly (2008) presumes two main parts of data visualization: statistical graphics, and thematic cartography. In this line the "Data Visualization: Modern Approaches" (2007) article gives an overview of seven subjects of data visualization:
0 Try PHPMyAdmin which has some really nice visualisation and editing feature. I am pretty sure you can even export to exel from it. When you say visualize the database schema, are you referring to a text-document of all your tables, sprocs, etc., or are you referring to a visual representation of your schema and dependencies? I know you mentioned MySQL (and it is very possible that it is supported now, but I am not sure), but RedGate has a number of tools that make that. My Visual Database 6.3. A simple development environment allows you to create databases without the help of specialists or the need for programming skills. MVD will enable you to create a self-contained database application that operates on Windows XP, 7, 8 and 10. Databases can be simple telephone directories or basic accounting systems
French philosopher and mathematician René Descartes and Pierre de Fermat developed analytic geometry and two-dimensional coordinate system which heavily influenced the practical methods of displaying and calculating values. Fermat and Blaise Pascal's work on statistics and probability theory laid the groundwork for what we now conceptualize as data. According to the Interaction Design Foundation, these developments allowed and helped William Playfair, who saw potential for graphical communication of quantitative data, to generate and develop graphical methods of statistics.

On the other hand, from a computer science perspective, Frits H. Post in 2002 categorized the field into sub-fields: Power View is an interactive data exploration, visualization, and presentation experience that encourages intuitive ad-hoc reporting. Power View is a feature of Microsoft Excel 2013, and of Microsoft SharePoint Server 2010 and 2013 as part of the SQL Server 2012 Service Pack 1 Reporting Services Add-in for Microsoft SharePoint Server Enterprise Edition
14 I usually use SchemaSpy to do this, but recently I found a really simple article on sqlfairy that just uses the dump file to create the structure graph Using Power BI Desktop to Visualize SQL Server Metadata You can easily use PowerBI Desktop to show graphically how your database is growing, which tables are taking the most space, how various parts of SQL Server is consuming memory, its use of indexes and so on 0 SchemaBall is doing visualisation its own interesting way. 0 When you say visualize the database schema, are you referring to a text-document of all your tables, sprocs, etc., or are you referring to a visual representation of your schema and dependencies?
The Best Data Visualization Tools for 2020. Where business intelligence (BI) tools help with parsing large amounts of data, visualization tools help present that data in new ways to facilitate. Author Stephen Few described eight types of quantitative messages that users may attempt to understand or communicate from a set of data and the associated graphs used to help communicate the message: Data visualization refers to the graphical representation of information and data. By using visual elements like charts, graphs, timelines, and maps, data visualization is an accessible way to see and understand trends, outliers, correlations, and patterns in data
Tableau. Tableau is often regarded as the grand master of data visualization software and for good reason. Tableau has a very large customer base of 57,000+ accounts across many industries due to. FAOSTAT provides free access to food and agriculture data for over 245 countries and territories and covers all FAO regional groupings from 1961 to the most recent year available Analysts reviewing a set of data may consider whether some or all of the messages and graphic types above are applicable to their task and audience. The process of trial and error to identify meaningful relationships and messages in the data is part of exploratory data analysis. 1 Thanks @fguillen! Let's add the explanation right here (before the link might break…). It's only 4 easy steps: 1.) Install graphviz, it's available in MacPorts (sudo port install graphviz) and in Homebrew (brew install graphviz). 2.) Export Dot file (in SequelPro go to File > Export > Graphviz Dot and export your database) 3.) Open terminal and convert dot file to SVG dot -Tsvg your_database.dot > your_database.svg 4.) Optionally convert generated SVG to JPG or PNG using any tool of your choice (Inkscape, ImageMagick, GraphicsMagick, etc.) – Arvid Nov 24 '16 at 13:22 add a comment | 9 I would recommend Toad data modeller
2 I looked for a long time for a decent, and preferably free, tool for linux and found this java application that is quite good (finally!!):To communicate information clearly and efficiently, data visualization uses statistical graphics, plots, information graphics and other tools. Numerical data may be encoded using dots, lines, or bars, to visually communicate a quantitative message. Effective visualization helps users analyze and reason about data and evidence. It makes complex data more accessible, understandable and usable. Users may have particular analytical tasks, such as making comparisons or understanding causality, and the design principle of the graphic (i.e., showing comparisons or showing causality) follows the task. Tables are generally used where users will look up a specific measurement, while charts of various types are used to show patterns or relationships in the data for one or more variables.
Being Java it is cross-platform (I run it on Linux with no issues) and it will connect to any database you can get a JDBC driver for. ie: pretty much any database.Or you could go even further, and reverse engineer an Entity-Relationship model with an accompanying diagram. ER diagrams were really useful to me when discussing the data with people who were neither programmers nor database experts. 1 Adminer (formerly phpMinAdmin), the web application for managing MySQL databases, draws simple diagram. 2 A different approach, but if you're using Ruby on Rails try RailRoad: http://railroad.rubyforge.org Use the MATLAB Visualizations app to visualize data in a ThingSpeak™ channel. You can view and explore data using interactive visualizations such as an area plot, line plot, or scatter plot in static visualizations using other MATLAB plots.You can also make visualizations public and use the URL to embed them on websites

In the second half of the 20th century, Jacques Bertin used quantitative graphs to represent information "intuitively, clearly, accurately, and efficiently". John Tukey and Edward Tufte pushed the bounds of data visualization; Tukey with his new statistical approach of exploratory data analysis and Tufte with his book "The Visual Display of Quantitative Information" paved the way for refining data visualization techniques for more than statisticians. With the progression of technology came the progression of data visualization; starting with hand drawn visualizations and evolving into more technical applications – including interactive designs leading to software visualization. Please recommend a tool to visualize database schema. It should be able to generate schema of existing DB. support - mySQL platform - Linux/Windows licence - free/open-source. Something like the image depicts. Colors are not that important. If anyone could tell me what software created the above diagram, that would be great 10 on Mac OS X you can use Sequel Pro
add a comment | 1 I use SQL::Translator with DBIx::ClassFor example, the Minard diagram shows the losses suffered by Napoleon's army in the 1812–1813 period. Six variables are plotted: the size of the army, its location on a two-dimensional surface (x and y), time, direction of movement, and temperature. The line width illustrates a comparison (size of the army at points in time) while the temperature axis suggests a cause of the change in army size. This multivariate display on a two dimensional surface tells a story that can be grasped immediately while identifying the source data to build credibility. Tufte wrote in 1983 that: "It may well be the best statistical graphic ever drawn."
2. Looker. Looker is a data visualization solution that helps businesses large and small make agile and timely decisions through an in-depth analysis of raw data for insights. It features a powerful business intelligence platform that lets users utilize SQL to organize unstructured data. Furthermore, Looker uses popular data modeling language for impactful visualizations and seamless data. Data visualization is the graphic representation of data.It involves producing images that communicate relationships among the represented data to viewers of the images. This communication is achieved through the use of a systematic mapping between graphic marks and data values in the creation of the visualization. This mapping establishes how data values will be represented visually.
You may think that, unlike NoSQL databases, relational databases aren't suited to graph analysis and visualization.. Whilst it's true that the tabular data model and schema restrictions sometimes make relational databases an inefficient option for visualizing connected data, with the right data modeling it is possible By the 16th century, techniques and instruments for precise observation and measurement of physical quantities, and geographic and celestial position were well-developed (for example, a “wall quadrant” constructed by Tycho Brahe [1546–1601], covering an entire wall in his observatory). Particularly important were the development of triangulation and other methods to determine mapping locations accurately.

Not applying these principles may result in misleading graphs, which distort the message or support an erroneous conclusion. According to Tufte, chartjunk refers to extraneous interior decoration of the graphic that does not enhance the message, or gratuitous three dimensional or perspective effects. Needlessly separating the explanatory key from the image itself, requiring the eye to travel back and forth from the image to the key, is a form of "administrative debris." The ratio of "data to ink" should be maximized, erasing non-data ink where feasible. 0 Years ago, I used to use Data Architect. I don't know if it's still out there. Indeed, Fernanda Viegas and Martin M. Wattenberg suggested that an ideal visualization should not only communicate clearly, but stimulate viewer engagement and attention. 2 DeZign for Databases might be interesting for you. You can reverse engineer and modify existing databases. Has got an auto-layout function and diagram layout is not meshed up when synchronizing your data model with the database.
A human can distinguish differences in line length, shape, orientation, distances, and color (hue) readily without significant processing effort; these are referred to as "pre-attentive attributes". For example, it may require significant time and effort ("attentive processing") to identify the number of times the digit "5" appears in a series of numbers; but if that digit is different in size, orientation, or color, instances of the digit can be noted quickly through pre-attentive processing. 0 I tried DBSchema. Nice features, but wildly slow for a database with about 75 tables. Unusable.
DataFlex is an object-oriented high-level programming language and a fourth generation visual tool 4GL for developing Windows, web and mobile software applications on one framework-based platform. It was introduced and developed by Data Access Corporation beginning in 1982 After plotting your geography data in 3D Maps, you can use the Layer Pane to change the look and feel of your data on the map. By default, 3D Maps shows a column chart, but you can show a bubble chart, region chart, or heat map instead. Here's an example of a region chart that shows voting preferences by county for the major political parties in the United States 2 Visio professional has a database reverse-engineering tool built into it. You should be able to use it with MySQL through an ODBC driver. It works best when you reverse engineer the database and then create the diagrams by dragging them off the tables and views panel. It will drag any foreign key objects and put them on the diagram as well. Data visualization can change not only how you look at data but how fast and effectively you can make decisions. But investing in these tools can be expensive for beginners so here's a list of.
