I’m a huge fan of JQuery, but I try to keep track of some of the other javascript libraries out there, especially any of those around visual display of informtion. Flash provided a lot of great online graphing capabilities, but there’s always the problem of corporate restrictions on what can show up in the browser.

I’ve played around with this library and it delivers on the promise of easy to use graphing and drawing with javascript. Take a look and also check out some of the demos on the site.
