What's your favorite chart framework/library and why? Do you use more than one?

in R, you're fooling yourself if you're not using ggplot -- all hail Hadley Wickham, our benevolent overlord! In Python, I haven't yet settled on a favorite tool. Recently I used matplotlib but it's a little clunky/verbose, so happy to hear others' recommendations.

Python: I used to work with matplotlib for academics, i.e., nothing fancy. Now I prefer Plotly.

JavaScript: Using more ChartJS than D3 right now.

For anything Java, Spock for tests and GPars for concurrency. Both originate from the Groovy ecosystem, are super-easy to use and fit projects of any size. Must-haves in any Java-Toolbelt.
