{"version":"1.0","type":"rich","title":"points on a map","description":"This map shows the locations of major world cities as circular points overlaid on a globe, with country borders, graticule lines, and a shaded sphere providing geographic context. City coordinates from a CSV file are projected using the `geoEqualEarth` projection, and their positions are rendered as SVG circles with a specified radius. The visualization is built using React, D3 v5, and the TopoJSON library for processing country boundaries and interior lines, with styling applied via CSS.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/79a0227bea974bf7b2ea4e3840a7ea22?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
