{"version":"1.0","type":"rich","title":"Points on a Map - Episode 36","description":"This example visualizes world cities as semi-transparent points overlaid on a natural Earth projection map. The visualization displays country landmasses, graticules, and interior borders, with city locations rendered as small circles positioned using the geoNaturalEarth1 projection and geoPath utilities. Built with React and D3 v5, it loads geographic data from a TopoJSON world atlas and city coordinates from a CSV file, using d3.json, d3.csv, and topojson feature/mesh functions to prepare the data for SVG rendering.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/819e75b500b34d04a3c1dd0b0d889682?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
