Beautiful, only complaint is it's 100kb minified - that's a lot of JS. Would love to know if there is any kind of modularization (if I only need 1 kind of chart can I lose some of the weight?).
I've been working on a Canvas library for full-powered diagramming for a year and a half and it currently weighs in at 597kb minified. (private alpha going on right now, so its nearing final size)
It's super awesome and covers an enormous amount of enterprise diagramming needs like customizable nodes, links, layouts, an undo manager, data binding, models, overviews, events, commands, tools, you get the idea.
But do you think people will reject it based on the size? Do you think not having a slimmer version would be a deal breaker?
Not at all. For what you are actually getting 100kb is awesome. However I like to develop really light pages especially for mobile. It's not even all about download size, mobile browsers can bog down even just parsing and keeping JS in memory.
The 100kb minified unzipped is a concern of mine, however. As the library evolves, keeping it trim and trimmer is a goal.
