Drilldown Choropleth by MSA

Hi marlline

According to this article, please check if you have done the correct steps.

To use the visuals, bring a dataset into Power BI, and put the custom visual on your page.

Put your data’s first-level location property in the Locations field, and the property you want to chart in the Values fields.

Then on the visual’s Formatting pane, open the Shape customization and put the URL to the first level of your map in the Level 1 box, the URL to your next level in the Level 2 box, and so on. If the name of the geographic property of your map doesn’t match the name of the field in your data, you can set that property name in the ID boxes.
