Hi everyone,
I have a custom map on a .json format. I make it to import in Power BI but the graph shows this:
Then I changed the projection to "equirectangular" and I could get the map but in a really small size:
Afterwards, I checked some past posts so I decided to import the file into mapshaper and typed proj wgs84 on the console, but got the following message:
Can anyone help me with that?
Thank you!!

Hi @Anonymous ,
When converting to WGS-84 in the Mapshaper console, you might get an error which says "Unable to project -- source coordinate system is unknown ". This means that Mapshaper can not recognise the original coordinate system, and you will need to specify it yourself to convert. For this you will need to check the source of where you downloaded the geo data.
For details, please refer to these documents:
