 ## About the data
 
-This sample uses a [web map](https://www.arcgis.com/home/item.html?id=8916d50c44c746c1aafae001552bad23) that displays the [Esri Global Power Plants](https://www.arcgis.com/home/item.html?id=eb54b44c65b846cca12914b87b315169) feature layer with feature reduction enabled. When enabled, the aggregate features symbology shows the color of the most common power plant type, and a size relative to the average plant capacity of the cluster.
