Option to download values for figures to reformat externally

[zmsubin]

Feature enhancement request: it looks like the "view source" and Vega options only display the axis data but not the values for readily extracting. It would be nice to be able to quickly download the data underlying a comparison timeseries chart so it can be reformatted externally (i.e., without having to install the whole repo).

Thanks for adding this; there might be a bug with the json formatting for my comparison chart. I'm getting a json string parsing error:
From browser:
SyntaxError: JSON.parse: unterminated string at line 1 column 72714 of the JSON data
From pandas:
`---------------------------------------------------------------------------

Here is what the chart looks like, in case this depends on the chart configuration.

Ah sorry, thanks for flagging! I think I've fixed it to handle larger files now (will deploy in the next 10 min)!
