C3.js: D3-based reusable chart library
Out of raw d3.js, nvd3.js, cubism, and rickshaw.js, I've by far had the best experience with nvd3.I was particularly pleased with the way nvd3 supports sliding data off line charts without any extra work.D3.js is an excellent, low level visualization library. But you will find yourself spending days to a couple weeks with custom styling, tooltips, legends, etc. Many high level charting libraries are nice because they have this out of the box.However, I want a library that lets me make visualizations that I can run on my monitor for 10 days straight without running into obscure bugs. Rickshaw failed me in this regard. I have a caching scheme in my client-side application. Rickshaw has its own local copy of data which requires the developer to write custom, messy javascript to evict. I found that rickshaw actually has some custom 'sliding window' logic. I was unhappy because I had to go to stackoverflow to discover that feature rather than using the documentation.nvd3.js simply worked for me.
