I have zip codes of customers (as origin) that I want to map to transit stations (destination). I added the flow map custom visual but it doesn't recognize the zip codes. The ESRI visual recognizes the zip code but I'm not sure how to create flow lines.
Hi Letitia King-Branch, I don't think this is possible in Power BI. However, there are workarounds which will approximate what you are looking to achieve.
I have a model where I locate stores in a radius of a statistical region. I achieve this by creating Lat/Long coordinates for stores and Lat/Long coordinates for the region using the centroid location. I then use Dax to show the stores within a distance of the region which can be represented on an ArcGIS map using the filtered stores as points. I've also created a Hosted Feature Layer of the regions which I use as a background to the point layer.
I have seen an Analysis feature in AGOL that creates this.
you can save it as a feature layer under your point layer... this may be closer to what you are after but, Power BI is limited to filtering only the top layer (be it a point or area layer) of the visual.
