According to superset pull request it's possible to personalize the tooltip for geographic data using some JavaScript.
I've tried many things to get my point data to the tooltip, yet none of them work.
Where does Superset store the extra JS parameters?
The object.props.OwnData
referenced in this PR does not work https://github.com/apache/incubator-superset/pull/4173
I've no idea where my extra parameters go into the JavaScript environment.
