This is an open-source “spin-off” from the SIMILE project at MIT. Here we offer free, open-source web widgets, mostly for data visualizations. They are maintained and improved over time by a community of open-source developers.

Exhibit
Create web pages with support for sorting, filtering, and rich visualizations by writing only HTML and optionally some CSS and Javascript code. No database and no server needed.
Timeline
Visualize temporal information on an interactive drag-able timeline.
Timeplot
Plot time series and overlay temporal events over them.
Runway
Display images in a Coverflow-like visualization.
Exhibit (version 2)
The previous version of Exhibit, currently used on thousands of websites around the web. This has most of the features of the current version but lacks the performance on large data sets.
