Modifiable vega-lite?

[mroswell]

We'll leave learning vega-lite to the user, but I wasn't sure how to create an instance where I can tweak the chart format. I do see the little white circle that offers the ability to open in the vega-lite editor. But the chart there is blank. The only way it carries over the data is as a partial url in the json definition. Can anyone document how to get a live instance that's modifiable? For instance, tweaking color, size, or chart type or anything else that vega-lite offers... using our own data.

Hmm... looks like we just need to carry over the 'http://example.com' portion of the URL into the "url" value. (Though I've had mixed success with this. Usually getting "[Warning] Loading failed" even if the JSON url is accurate. My table has less than 550 records. I wonder if the incomplete URL version just somehow got cached somewhere along the line.)

UPDATE: I was missing the 's' after 'http' and the vega-lite editor didn't like that.

So it looks like we just have to carry over the full url, and we'd be able to edit the vega-lite chart to our heart's content.

Also doesn't work if you're using a local database that isn't exposed to the outside world (at least as far as I can tell). I would also love to see the ability to modify the format/configuration of the graph either through Vega editor or by passing values through metadata.json (even better, I think).

This is a bug that could be fixed by replacing:
"url": "/covid/ny_times_us_counties.json?_shape=array&_shape=array",
with
"url": "https://covid-19.datasettes.com/covid/ny_times_us_counties.json?_shape=array&_shape=array",

on the https://vega.github.io/editor/#/ link at:
https://covid-19.datasettes.com/covid/ny_times_us_counties#g.mark=bar&g.x_column=state&g.x_type=ordinal&g.y_column=county&g.y_type=ordinal

But I'm having trouble figuring out where that would be done. Maybe it's somewhere in the vega-embed project... needing to inject the domain name in there. Can anyone find where the fix is for this?
