{"version":"1.0","type":"rich","title":"Florida Counties","description":"A choropleth map of Florida’s counties uses a Mercator projection fitted to the state’s boundaries, with each county rendered as a gray SVG path. Hovering highlights the county in greenyellow and displays its name in a tooltip. The visualization loads TopoJSON data, converts it to GeoJSON via `topojson.feature`, and projects it with `d3.geoPath` and `d3.geoMercator`. Mouse events (`mouseover`, `mousemove`, `mouseout`) dynamically position and toggle the tooltip’s opacity, while `fitSize` ensures the map fills the viewport.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d0ed8dada53f40adb62f2a29740cb7b0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
