Feature: Add json provider

[german-bortoli]

Sorry I am new in vizwit, but I found that it only works for socrata or carto data types, should not be cool to have a json provider ? that based on a json data we coud graph everything from there ?

Hi @Germanaz0 ! This would be a great feature. I recall earlier on in the project trying to get VizWit to work with Google Sheets. I ran into a challenge there that would also be present here: the need to do the group by, aggregation, and filtering client-side would involve a significant refactor of the way VizWit works. I think it's definitely possible, and can't remember the exact hangup (and oddly I don't see an issue about it), but it's not nearly as easy as simply adding another provider would be :-/

I'd be happy to help and give direction if you're interested in diving in to try and add this.
