{"version":"1.0","type":"rich","title":"Map Data Sources - Alternating CSVs - Show & Hide","description":"This visualization displays customer and employee locations on a world map using D3 v4 with a Mercator projection and TopoJSON world boundaries. Two CSV datasets are loaded and rendered as circles, with customers and employees represented as separate layers. Users toggle between datasets via two buttons (“Customers” and “Employees”), which triggers a smooth animated transition: all circles shrink to radius 0, then the selected dataset’s circles grow to radius 4. The map uses a light green landmass and light blue background, with white-stroked country boundaries, creating a clean base for the animated show-and-hide interaction.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-4ba4f84a7a94dd83684910be0992f411?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
