Why someone would design a charting library and design the dataTable without reusing someone else's format is completely beyond me.

This one is specially bad because it mixes format with content, I thought we learned it was bad idea when we came up with CSS.

Why not use the same data format as Google Chart Tools and make it dead simple to switch from one library to the other or to integrate with several data sources available for Google Chart Tools?

And if you are still mad about Reader and feel rebel just use the same format as highcharts or .

Don't get me wrong, I think this is beautiful, and other than this small design rant I appreciate your work a lot and the effort to bring it to the world open source. Thanks a lot.

And now I see why people were so excited about this! This is very impressive, I only hope that I remember it or can find it by Googling "charts javascript library" when I find a time to use it!

It's open source, fork it and make these changes yourself.

The charts are nice and everything about the site looks well presented, including the thorough documentation. My only gripe is the lack of chart types at the moment (e.g. candlestick), but with the fundamentals well and truly in place, I imagine more chart types will be added with time.

Congrats on being able to open source this and thank you for doing so. Honest question: Is animation really a needed feature for this? The opening animation adds no information value and has the negative effect of making the user think the graphics are actually interactive. I'm sure the animation itself isn't memory/processor intensive but it seems like a really unnecessary feature for a charting library that creates…

May be there is a way to switch it off? There seems to be the following option

//Boolean - Whether we animate the rotation of the Doughnut

animateRotate : true,

Earlier quoted context omitted.

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.

... and then he'd just be re-implementing (highcharts)[ http://highcharts.com ]

A freely available charting library with the same capabilities as highcharts would be a welcome thing for many people.
