D3 charting library by UserVoice
See examples at http://sonic-charts.divshot.io.
You'll need to have Node and NPM setup on your machine. To install Node development dependencies run:
npm install
Then build the assets with Gulp:
gulp build
Or, if you want an auto-building server with examples, run:
gulp server
And go to http://localhost:5000/examples.
After running finished packages are available in dist.
