Map visual in power bi help

Hi DiKi-I 

Thank you for reaching out to the Microsoft Fabric Community Forum.

I have reproduced the scenario on my end using the sample data, and the solution is working as expected. The setup allows you to select an origin premise from the slicer, which highlights the selected premise prominently on the map while also displaying all of its connected destination premises around it. To help you better understand the implementation I have prepared and attached a sample .pbix file and snapshot that demonstrates the full implementation. Please review the attached file at your convenience and share your observations so we can refine the solution further if needed.

I hope this information is helpful. . If you have any further questions, please let us know. we can assist you further.

Regards,

Microsoft Fabric Community Support Team.
