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?

Hey thanks! I know internally at Quantifind we've built a lot of dataframe functionality ourselves, to help the transition for people coming from R.

I've played a little with Breeze and it didn't really fit my style either.

Let me check with some of the R-minded folk and get back to you!

I've been looking for something like python's pandas as well, so curious what they say.

Loving Wisp! I've been needing something exactly like it and will definitely be making use of it. So thanks!

They shared the collective disappointment in the lacking data frame DSL

Currently evaluating RinScala if you'd like to check it out!

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?

If I'm not mistaken, it generates a js spec which is rendered by an embedded server. Looks great! My second thought though was scala.js, any plans to make this 'pure' js?

Correct. There's definitely a lot to improve around rendering. I didn't know about scala.js, thanks for the pointer!

I'm not sure what you mean by pure js though - I try to make things scala whenever I can.

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