Looks good. I did some evaluation of javascript graphing packages at my last position (migrating away from flash). We ended up paying for one. This looks great, contains a lot of useful graph types. I like the fact that the charts can be rendered and saved as png images. This is a feature often lacking in a lot of javascript graphing packages. Couldn't see if you can pass in the data via ajax (update after rendered), but I'll look some more. They claim to have patented one of the features:
Our "Drag-Recalculate" feature (patented)

For example, imagine a simple bar chart of fruits that people have:
Alice: 5 apples, 6 oranges
Bob: 10 apples, 2 oranges
From a quick perusal of the examples, you can drag Alice's apples onto Bob's apple stack. Now Bob has 15 apples? wat? It seems you can even drag Alice's apples onto Bob's oranges. Try it yourself: https://ecomfe.github.io/echarts/doc/example/bar4.html#-en (not sure what those funny characters on the left say, but imagine they say Alice, Bob, Charlie, etc., and the colors are apples, oranges, radishes, etc.)
The behavior also only really works if you're working with sum aggregations. If you're talking about averages or mins, you again get non-sensical combinations.
It's a neat behavior, no doubt, but it's very limited in the cases when it's appropriate. Some of their examples show cases where you can use it non-sensically. Unless the visualization is being produced by an expert who knows when NOT to use shiney features, I fear people will get too excited by the shineyness and create completely inappropriate visualizations. Remember when 3D bars were the shit?
