I've tried connecting a Shape map visualization (preview) to a 400 MB topojson file (huge file, I know!) to create a custom map. My assumption was that Power BI would crash due to the data amount in this file. After testing it, Power BI did crash. Now, I'm trying to investigate what's the MB limit for a topojson file linked to Shape map visualization before crashing Power BI. The custom Shape map seems to be pretty cool, but the underlying topojson capacity must have a MB limit. Any ideas on what this size limit is?
