{"version":"1.0","type":"rich","title":"My choropleth","description":"This choropleth displays a world map derived from the Natural Earth dataset, using a natural Earth projection. The code initializes an SVG canvas and fetches TopoJSON data from the unpkg-hosted world-atlas package via `d3.json`. It imports `geoNaturalEarth1`, `geoPath`, and `select` from d3.v5, although the map’s geographic paths are not yet rendered—only the loaded data is logged to the console. The example demonstrates the initial setup for building a choropleth, with the styling ready for future map layers.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0fbdb0d252c3472eab8ecc8e6652eaa1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
