some more analysis:
I adapted the CSV-URL from your example by expanding the sheet ID with the parameters and the URL prefixes in the screen shots. And then it worked (although it didn't use the pie chart but just the very first table): https://docs.google.com/spreadsheet/pub?key=10JQZob-lWt0GSWcOvKgw9JwZbvkGGlXn3dq2sUEQUBU&single=true&gid=1&output=csv
BUT (and this is more important): We can't get this to work with the new google tables. The reason is, Google obviously changed its URL format for CSV sharing. Now the sharing URL for CSV output looks like
https://docs.google.com/spreadsheets/d/e/2PACX-1vR3HjEvTe8oqS1gmLfigr7LFHRTtuYk3OauRcgXlrWhxkVsEpMPK-Pviibg33So-yD73y1N_3PBPZHt/pub?gid=0&single=true&output=csv (not working sample URL).
If I copy one of those new share links into your module I get the error "JA_GOOGLE_CHART_MISSING_DATA_INPUT" in the frontend.
So it seems like it is all about updating the module (and the documentation, please) to comply with the new Google API requirements.
What do you think, how fast can this be done?
Thank you!
