{"version":"1.0","type":"rich","title":"Sized Points on a Map","description":"This map of Amsterdam displays the locations of universities and colleges, shown as small yellow circles, layered over the city’s neighborhoods, which are colored by district. A tooltip appears on hover, and clicking a school highlights it while fading the others. The visualization uses D3 v5 with a Mercator projection (`d3.geoMercator`) and path generation (`d3.geoPath`) to render TopoJSON neighborhood boundaries. City data comes from a local JSON file, and interactions like zoom and tooltips are implemented with D3’s zoom and event handlers.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/884ce367b2284e068050d2897b514e8b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
