So I've been trying to find a way of plotting custom polygons/polylines on a map visualisation in Power BI with all teh details and labels needed on a map for reference. I've seen the Shape maps features, but this is very plain and seems to offer no reference details, like road names.
I've also had a look into doing this with reference layers in ArcGIS maps, but the functionality isn't great, as I wanted highly interactive polygons (like you would get with the pre-determined polygons plotted when data is entered in the "location" field well). This means filtering if you press on the polygons and pressing other visuals to filter the map, etc.
I've also tried Mapbox, but this visual had its own limitations, that weren't ideal for me. After some research, I found that you can use Esri JSON to ploy custom polygons as a relatively nmew feature of ArcGIS maps in PBI, as mentioned in these links:
https://doc.arcgis.com/en/power-bi/get-started/prepare-your-data.htm
https://www.esri.com/arcgis-blog/products/power-bi/announcements/whats-new-in-arcgis-for-power-bi-au...
So my question is, except from shape maps and reference layers in ArcGIS maps, is there a way to get custom polygons from your own data (like shapefiles) plotted in your ArcGIS maps in Power BI? Perhaps using this mentioned Esri JSON feature? I just haven't seen a place that talks about how to do this, despite people saying this functionality exists, any idea?
