Protovis Protovis composes custom views of data with simple marks such as bars and dots. Unlike low-level graphics libraries that quickly become tedious for visualization, Protovis defines marks through dynamic properties that encode data, allowing inheritance, scales and layouts to simplify construction. Protovis is free and open-source, provided under the BSD License. It uses JavaScript and SVG for web-native visualizations; no plugin required (though you will need a modern web browser)! Although programming experience is helpful, Protovis is mostly declarative and designed to be learned by example.

Venn Templates and Venn Diagram Software - Free and no download required with Gliffy Online A Venn diagram is a simple way to represent the relationships between groups of things with a clear, visual display. Let your ideas overlap In a Venn diagram, large circles represent groups of things with a shared attribute. Areas where these circles overlap represent individuals that belong equally to both groups. For example, a Venn diagram with one circle representing things made with yeast and another representing alcoholic beverages would have an overlapping zone where you could find both beer and wine. Graphical visualization of text similarities in essays in a book Implementation criteria The graphics generated were intended for high-quality reproduction in the book. Since we wanted them to consist primarily of typography and colored areas, we selected a vector- rather than a pixel-based format. In addition, as an output file, the format was to be written by means of an algorithm to ensure a fully automated process. This made it essential to work with an ”open” format that had a well-known internal syntax and could be easily processed by book layout programs [ad.03]. We used Adobe Illustrator for graphics and Adobe InDesign for book layout.
