{"version":"1.0","type":"rich","title":"Points on a Map","description":"This example displays a world map with points marking cities, rendered as an SVG using D3’s geoNaturalEarth1 projection and geoPath. The map shows landmasses, graticules, and country borders from the world-atlas TopoJSON, while city locations from a CSV file are plotted as semi-transparent circles. React manages the component state, fetching the data with useWorldAtlas and useCities hooks, and the d3.geoPath calculates the projected coordinates for each circle.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3221c1a4e5ab45049a903c6ea17e237a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
