Grafico Charts
Grafico is a charting library that provides line, area, stacked and bar graphs, as well as various types of sparklines.
Grafico also includes features like pop-up hovers. All of the features are covered in the documentation.
The API looks like this:
var graph = new Grafico.GraphType($(element), data, options);
So drawing a line graph is easy:
var linegraph = new Grafico.LineGraph($('linegraph'), { workload: [8, 10, 6, 12, 7, 6, 9] });
Grafico is actually based on a library called Ico that I made. Ico has some history behind it: I attempted to replicate the advice in Stephen Few’s books to create a library that intuitively produces usable and clean graphs. I’m still working on Ico — I’ve been benchmarking it to improve speed and remove the Prototype dependency.
