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 number of requests from people asking for help has become unsustainable, and I am therefore unable to continue offering free support for Icon Map. You can still raise issues on the Github page, but you will need to rely on the Icon Map community to respond.

To ensure that people are able to receive a reliable level of response and support going forwards, with others, I have launched a new company, Tekantis Ltd, and developed a new map visual for Power BI, Icon Map PRO.

As a commercial visual, this will be supported by a team of developers and support staff, and is being regularly updated with new features and improvements. The new visual also includes our own background mapping, resolving the need to rely on third party providers.
