<legend>Deck.gl custome WebGL layer</legend>
This sample creates a WebGL layer that integrates the layers from <a href="https://deck.gl/">Deck.gl</a>.
Deck.gl is a WebGL-powered framework for visual exploratory data analysis of large datasets.
Deck.gl allows complex visualizations to be constructed by composing existing layers and makes it easy to package and share new visualizations as reusable layers.
<br/><br/>
If using an older version of deck.gl, you can find an older version of this sample <a href="https://github.com/Azure-Samples/AzureMapsCodeSamples/blob/978458eef14881df9cc7316d2fdbb67b9cb09653/Samples/3D-layer/deck.gl/deck.gl.html" target="_blank">here</a>.
