Need help with custom shape map json
Hi rahulcv ,
Ensure that your TopoJSON file includes both layers (states and counties). You can use tools like Mapshaper (https://mapshaper.org/) to inspect and edit your TopoJSON file.
For more details, please refer:

Hello Anonymous,
Thank you for the helpful links; they were certainly pointing in the right direction. However, I encountered an issue where the solution didn’t fully work as expected in Power BI. It seems, that Power BI might not parse certain JSON file attributes correctly, specifically those related to stroke-width and color in the style tag. These styling attributes appear to be ignored during the rendering process.
Given this, I’m looking for advice on how to achieve differentiated state borders on a U.S. counties map in Power BI. My goal is to make the state borders more prominent compared to the county borders, like the picture below ( which was achieved by placing an image on top of the map, but it wouldn't allow any of the interactivity )
If any of my assumptions or steps are incorrect, please feel free to correct me.
I also followed the steps outlined in the above mentioned article and here’s the output from Mapshaper:
However, the resulting map in Power BI looked like this:
Notice, there are two lines at the hand-drawn arrow, which suggests that the merge was successful and is being rendered by Power BI, but the differentiation in line styling is not visible.
Any insights or suggestions to resolve this would be greatly appreciated.
