{"version":"1.0","type":"rich","title":"ArcGIS: JavaScript starter app","description":"This example demonstrates interactive 2D and 3D map visualization using ArcGIS JavaScript APIs alongside D3.js for a dropdown menu interface. The application loads a NatGeo World Map tile layer over various Esri basemaps, with a 2D MapView centered on coordinates [34.8021, 38.9968] at zoom level 5. The code includes commented-out 3D SceneView functionality with elevation settings and camera positioning. The dropdown menu, built with D3’s `select`, `append`, `merge`, and `attr` methods, lets users switch between different basemap options.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4e372181f9dc42dc81ccba58d51a4113?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
