How to author Map Keys in custom Shape file?
I have created a custom SHP file from scratch (using QGIS), then converted to TopoJSON using MapShaper.org.
Add a Shape Map visualization to my report, and choose custom map, and find my TopoJSON file on disk.
The shapes show correctly in the widget.
After adding a data column to the Color Saturation well, nothing shows in the map.
I suspect the Map Keys are not correct. When clicking on "view map keys" nothing shows. For all other map types (built in and downloaded, created by others), a dialog shows the keys that can be used to correlate to the regions in the map.
What do I have to add or do in the SHP file (in QGIS) to add map keys such that they can be used in the Power BI desktop visualization?
Just replied to a similar thread (did not realize I somehow started 2 threads with the same issue?).
This thread has the answer. It has to do with converting to TopoJSON using MapShaper.org, not on the QGIS side.
Thank you for the follow-up.

Hi DanH,
It seems that you have post your issue in the link below

Try opening the entire “Shapefile”, which is actually a compressed folder with multiple files such as .shp, .dbf, etc. in it. If you open the shp only, you only get the shapes, but the data/keys are actually contained in the dbf.
