Syntax errorr: Maximum call stack size exceeded

Hi, I am trying to upload a dataset and come up with the error above.
This happens both when running it in webppl.org and on my computer.

Any suggestions?

This is the data-
var data = {

Interesting! I'm seems like this has something to do with parsing large array/object literals, and I'd guess it's a bug in WebPPL. As a work around, you could represent your data as a giant string and parse it with JSON.parse. Something like:

var data = '{"1": [1,2,3], "2": [4,5,6]}'
JSON.parse(data)

If you are only working at the command line, then you could use the webppl-json package to replace the giant string with a file on disk.
