The current version can plot interactive graphs of various types. Graphs support control points, which users can click and drag to interact with the graph. Interaction is controlled by simple but flexible scripts. There are example scripts on the website.

The application is Java based, and can run on the desktop or as an applet on a web page.

Sympl is still at a very early stage, with plenty of plans for the future. I would welcome any comments or suggestions. Please also consider cross posting comments to the Sympl forums (http://www.sympl.org/forum).
