{"version":"1.0","type":"rich","title":"Points on a Map","description":"This visualization displays world cities with populations exceeding 50,000 as semi-transparent dots on an equal-earth projection map. The map shows landmasses, graticules, and country interiors using the `d3.geoPath` and `d3.geoEqualEarth` projections, while city points are positioned via the same projection and scaled using `d3.scaleSqrt`. Built with React and D3 v5, it loads GeoJSON world data from the `world-atlas` package and city coordinates from a CSV, rendering everything as SVG circles with opacity for overlapping points.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4ba26f5b01b14ad1b3ac0e247605ace7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
