I make GoJS, a HTML canvas-based diagramming library with all sorts of useful features. Node and link concepts (with data binding, templating), layouts, an undo manager, lots of customizable tools, drag and drop/cut and paste.
In other words, a very rich set of diagramming features atop HTML5 canvas.
I think its cool, because it took two years of canvas tomfoolery to get working well, and I think its much faster than similar diagramming libraries for canvas out right now. A lot of technically interesting stuff was encountered while making it, but I haven't had the time to write about my collected intricacies yet.
Firefox warning[1] for that specific sample though. I need to change the default sample this week.
[1] Super frustrating! The new IonMonkey JavaScript engine crashes under very certain conditions that are met during my link avoidsNodes algorithm. This means that Firefox 18 and 19 (but not 17 and 20) will crash on the Flowchart sample, because the link routing is set to use avoidsNodes. It's unfortunate but even though they're aware of the bug they aren't going to bother fixing it for FF19.
By the way, if there are other canvas library authors out there who have had interesting (or downright weird) issues with various canvas implementations, I'd love to hear from you!
Wow. Very very nice job there. I had project a while back and couldn't find too many options when it came to Javascript diagramming and had to settle with jsPlumb. I wish this was around at the time [edit] or at least more visible from my quick searching.
