{"version":"1.0","type":"rich","title":"dv2020-ep36-viz38 - points on a map","description":"This visualization displays a world map with over 50,000 cities plotted as points, using the Natural Earth dataset via the `topojson` library for geographic boundaries and a CSV of global city coordinates from Simplemaps. The map uses the `geoNaturalEarth1` projection and `geoPath` from d3 v5 to render countries, borders, shorelines, and graticules as SVG paths, with city data filtered by population and drawn as small circles. The React-based app loads data asynchronously and renders the interactive SVG within a fixed canvas, styled with a dark background and semi-transparent fills.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/dba68e1c579849ea8fb05f728a03848c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
