Arquero playground?

[mhkeller]

It would be great if there were a place one could try out arquero in the browser similar to the tidy.js playground. I often want to check a generic version of a transform function to make sure it works the way I think it does and this would be a great place to do that. The current alternative is using an observable notebook but given that it's not quite javascript and is a separate service, I think something just for arqeuro would be helpful.

I'm using runkit for this at the moment, for instance here's my current workaround for Arquero's pivot single valueKey simplification feature (mentioned here) looks like this:
