It looks nice, but perhaps not as comprehensive as Rickshaw http://code.shutterstock.com/rickshaw/ - also based on d3. Of course there are so many different charting libraries, it's really hard to choose, but I guess it depends on your needs.
Or you could look at NVD3 (https://github.com/novus/nvd3) which had 1.2k followers before the repo was taken down and put back up.
I just checked Rickshaw, their main page throws a lot of js errors in Google Chrome 24 in the console, making the examples unusable. Can anyone recommmend a more stable, D3-based charting library ?
The Rickshaw page is working fine for me in Chrome Canary (currently at Chrome 25) and Chrome 23, there's a single JS error but it's not preventing the examples from loading. Are you sure something else isn't the problem?
Have you checked the JavaScript console?
yup, that's where I saw the single error.
I checked Canary - the charts look fine, there is only a single js error in console. In Beta though, there is a lot of errors in d3.v2.js and rickshaw.min.js + that one that is reported in Canary (absinthe.min.js)
Check your extensions. Are they blocking any of the scripts? Try it without any extensions loaded.
