Awesome job, guys. I was just wondering recently if there's something like matplotlib but for Scala and there you go.

By the way, have you ever came across something similar to python's pandas but in Scala? Specifically I'm looking for DataFrame functionality, where you can read a dataset where column might have different types and then slice and dice this data in a way you want. The closest I found is Breeze but it supports only numerical types . And Saddle, but it supports only 3 columns as far as I understood. Anything else?

Is it possible for Wisp to re-render only the modified graph? It seems the whole page is re-rendered in the demo. Does Wisp cache/memoize the graphs or re-compute the data points when it re-renders?

Excellent demo! I love how easy this is to use.
