{"version":"1.0","type":"rich","title":"World Map","description":"This visualization displays a world map with city locations overlaid as semi-transparent dots. The map uses the Natural Earth projection via `d3.geoNaturalEarth1`, with graticules, land polygons, and country boundaries rendered through `d3.geoPath` and TopoJSON data from the world-atlas package. City coordinates from a CSV file are projected and drawn as SVG circles. The React component manages data loading with custom hooks, while D3 v5 handles geo and CSV parsing.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/de8eedb4426343d3aecd95abc26a0f82?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
