This example uses the ArcGIS API for JavaScript 4.15 and D3 v5 to create a map view of the Kilauea volcano eruption site. The Swipe widget compares two TileLayers—shortwave infrared and near-infrared satellite imagery from the WV03 satellite—by dividing the view at a draggable position. Layer visibility is controlled through the widget, while a LayerList provides additional map layer management. The map displays a satellite basemap centered on the volcano with constrained zoom levels.
