{"version":"1.0","type":"rich","title":"Plotting Points on a Map","description":"This visualization renders the contiguous United States from a TopoJSON dataset, mapping state boundaries and a light gray national background onto an SVG canvas. It uses the `d3.create` API to build the SVG element and the `topojson-client` feature function to convert the topology into geographic paths, which are then drawn with `d3.geoPath`. The code applies white strokes for state borders with rounded joins and caps, producing a clean, minimal choropleth base map without additional data layers.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4c2766933c53450eab827b6c318e6a2c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
