{"version":"1.0","type":"rich","title":"Points on a Map","description":"This example visualizes a world map with dots marking cities whose population exceeds 50,000. The city locations are plotted as semi-transparent teal circles over a natural Earth projection, with landmasses, graticules, and country interiors rendered in gray tones. The visualization is built with React and uses D3's `geoNaturalEarth1`, `geoPath`, and `geoGraticule` functions to project geographic data from the World Atlas TopoJSON. City coordinates come from the Simplemaps World Cities Database, accessed via a CSV file, and are projected onto the map using D3's projection method.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/40a803043f91433bbf57eb2c40629d62?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
