{"version":"1.0","type":"rich","title":"Points on a Map","description":"This visualization displays cities as semi-transparent points on a natural Earth projection map. The map is rendered as SVG using React, with geographic features generated via `geoNaturalEarth1`, `geoPath`, and `geoGraticule` from d3. Country landmasses are drawn from TopoJSON data loaded with `feature` and `mesh`, while city coordinates come from a CSV file processed with `csv`. The points are positioned by projecting each city's longitude and latitude through the projection function.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/72da470f3da94a848422ce89317a203c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
