How do I show my closest 3 competitors on a map?

Question

I work for a retailer and would like to create a map in Power BI for all of our stores and their 3 closest competitors, like the example below (Ideal Output). The blue dot is our store and the red dots are our competitors. Ideally, the map would change automatically when a different store is selected in a drop-down slicer. Please see the example data below (My Data).

Thanks,

Mark

Ideal Output:

My Data

Table 1: All of our stores. Very basic. Every store has its own unique number, along with basic store details including geocodes.

Table 2: All competitors. Every competitor has a unique number along with basic information including geocodes.

Table 3: Our stores and their 3 closest competitors.
