Free, Open-Source Data Visualization Web Widgets

Massachusetts Institute of Technology (MIT) developed as the part of their Simile project open-source web widgets for data visualizations. The Simile project “focused on developing robust, open source tools that empower users to access, manage, visualize and reuse digital assets.” [Simile] . Check out Timeline which visualizes temporal information on an interactive drag-able timeline; Exhibit which creates web pages with support for sorting, filtering, and rich visualizations by writing only HTML; Timeplot which plots time series and overlay temporal events over them; and Runway which displays images in a Coverflow-like visualization and is in my view probably the least useful one.
