@guerda Things often start out simple, and at one point you just realize that you need the big machinery to get the job done. That is matplotlib. But if you do not reach that point, plotly is awesome. One of the things I like most about it, is that all properties are simple dicts -- and JSON. So if you made a nice chart, it works in JavaScript as well.

@guerda Love mpl for flexibility, but nowadays mostly use plotly for interactivity.
