For one of my projects we wanted to create some nice charts. Feels like something you often want but do not do because it takes to much time. This time we really needed it. We had a look at D3.js library, a very nice library but so many options and a lot to do yourself. Than we found c3.js, check the blog post by Roberto: Creating charts with C3.js. Since I do a lot with AngularJS, I wanted to integrate these c3.js charts with AngularJS. I already wrote a piece about the integration. Now I went one step further by creating a set of AngularJS directives.
