Icon Map

Introduction

Icon Map is a free custom visual for Microsoft Power BI. Custom visuals allow you to extend the capabilties of Power BI with additional visuals, not developed by Microsoft. This visual was developed by James Dales and is based on an Open Source library, Leaflet. Whilst there are other map visuals available for Power BI, Icon Map was created to provide additional functionality not available in those visuals.

The latest version of the visual with the latest updates and bug fixes is available from the downloads page of this site.
