So why would I use this instead of D3.js?

#53"Pie charts are great at comparing proportions within a single data set."
No they're not.

Apparently, it was a misunderstanding on his part. "I misunderstood some issues I wrote about earlier today. Chart.js is now back online and available under MIT. http://www.chartjs.org ." - https://twitter.com/_nnnick/status/314049798502248448
I really don't see how someone can misunderstand this. You either can do it or you can't.
It wouldn't always be that clear cut. His employer's policy might be something like "outside projects are allowed as long as you don't use knowledge that you gained from working there".
That could easily be interpreted more broadly than it was intended. He could interpret it as "I learned Javascript while working there, so I can't release a project in Javascript" or something like that, when they really intended it to prevent use of non-publicly available information related to their business.

The project mentions that this was an intentional design decision. The graph's are written to a canvas element, which means a low memory footprint and the ability to save graphs as images. I believe they'd need to switch over to using SVG elements for graphs if there are plans to add DOM events to chart elements.
Clicks and hovers can be done on canvas, using hack that renders on second (invisible) canvas each object with its own, constant color and then checking color of the pixel at coordinates of cursor. It would probably need some kind of scene abstraction though.
Alternatively, just put some invisible DOM elements on top of the canvas and put your click handlers on those. It's imagemaps all over again ;)

or something built on d3 - like http://nvd3.org/

That seems less of a polite way of saying, and more like a butt-covering lie. Am I supposed to understand from 'misunderstand' that the company might be climbing down from a stupid mistake it made, or actually be misled?
It's not necessarily any of your business. The code is back, why do you need to know the full and whole truth about his dealings with his employer? And what's wrong with letting someone save a bit of face when they came out on the right end of something after all?
Thank you.
It is nobody's business here but Nick's what happened. Take his words at face value and assume he misunderstood his boss unless you have reason to believe otherwise and it actually matters.

D3 uses SVG which doesn't run on older Android and iOS devices at all, and uses a bunch more memory and CPU than a single Canvas element.

#59Ok, is this the best marketing campaign for an open-source project or what?!? I starred it yesterday but my guess is you've got a lot more people on board now!
best marketing campaign? I guess I am not seeing what you're seeing. To what are you referring to?
It would've been just-another-chart-library without the "my company made me take it down" angle.

This is a significantly higher abstraction than D3. Charts.js is comparable to NVD3, dc.js, xCharts, all of which are built on top of D3.
