I am new to Apache superset and I am trying to add a JavaScript tooltip to a geo map visualization.
I am using this piece of code in the "JavaScript tooltip generator":
d => "<div>field: <strong> ${d.object.props.ColumnName_Test} </strong></div>"
The value of the column name is not visible on the tooltip, but the hardcoded column name is visible:
I have googled a lot, but there is no documentation about how to use the JavaScript tooltip generator in Apache Superset.
Does someone know what I need to change in this piece of code to show the value of the column, instead of the column name?
