if only most of their documentation and code comments weren't written in chinese. It's great that they open sourced it - looks really good, but it will be hard for non chinese to grasp the more complex aspects of this library.
Imagine how hard it's been for Chinese speakers to learn to code and use most modern libraries. I'd say the billion+ Chinese folks can represent a large enough audience for this library, if English-speakers don't want to figure it out (and maybe help with translations).
When it comes to code, I generally want lots of good examples more than documentation, and there seem to be a reasonable amount of examples (I haven't spent much time trying to make sense of them, yet).
I'm implementing a new charting system for our products, and haven't yet settled on the graphing library (leaning toward Rickshaw, but also considering Metrics Graphics), so I'll give this a shot. It looks really promising, particularly with regard to large data sets, since that's something most graphing libraries fall down on...we current reduce our data set to 1024 or fewer data points before sending to the graph. It might be awesome to have all the data in the client and let them zoom in and out at will.
