Visualization

Stanford Vis Group: Protovis

Protovis is a free, open source tool for composing custom views of data from simple elements such as bars or dots. Marks are defined through dynamic properties to allow inheritance, scales and layouts for simplified visualization construction. This tool uses JavaScript and SVG in order to ensure web-native visualizations. Protovis is no longer under active construction; many of the concepts used in its development have been implemented in its successor, D3.js.

DocuBurst

DocuBurst is a free web-based visualization tool for exploring the contents of a text. Visitors can upload their own text or view those provided by others. DocuBurst presents an interactive chart called a ‘radial sunburst’ diagram which organizes the nouns extracted from the user-supplied text based on their meaning, and colours them based on frequency, revealing common themes in the text. The visualization also shows the proper nouns (e.g. character names) in a linked word cloud. The visualization may be zoomed, filtered, or refocused to target types of words of interest (e.g. “animal” words or “feeling” words). The visualization also provides a comparison tool to contrast word use across two documents. DocuBurst views can be bookmarked, annotated, shared, and embedded in your own website.
