Any idea how much data can be loaded in a browser or node and still be performant?

I guess it depends on your machine, but in my experience loading a CSV file with more than 20,000 rows only takes a couple of seconds.using the Node console. But some data manipulations (especially sorting, joining or pivoting a DataFrame) are very compute-intensive, so they might take some time to complete with a big dataset.

Nice. I like the API! Looking forward to trying it out.

I love this!

Thanks!
