This sample shows how to create a simple custom control that centers and zooms the map to fit any data that is loaded on the map.
This works with data in a HtmlMarkers, DataSource and ImageLayers. Does not support TileLayers and VectorTileSources.
This samples uses the open source <a href="https://github.com/Azure-Samples/azure-maps-bring-data-into-view-control" target="_blank">Azure Maps Bing Data into View Control module</a>.
