This sample shows how to detect if the browser is supported by the Azure Maps Web SDK. If it is, load the map, otherwise fallback gracefully.
There are many ways in which to handle this situation. Some common approaches include:
<ul>
<li>Show an error message and recommend the user tries a more modern browser.</li>
<li>If the map part of a page that has a lot of other content, consider hiding the map div.</li>
<li>If showing a smaller data set on the map, consider generating a static map image using the <a href="https://docs.microsoft.com/azure/azure-maps/how-to-render-custom-data" target="_blank">Azure Maps Render service</a></li>
</ul>
