{"version":"1.0","type":"rich","title":"Fork of Choropleth Map","description":"This fork of a choropleth map visualizes World Bank GDP per capita data for 2020 across countries worldwide. The map colors each country using a quantile color scale with a YlGnBu sequential scheme, with gray filling regions lacking data. The visualization loads GeoJSON topology from the world atlas and CSV data, processing both through `Promise.all` before rendering with `d3.geoNaturalEarth1`, `d3.geoPath`, and `d3.geoGraticule`. The code implements a reusable map component that updates through a state management pattern using `d3.select` and `d3.scaleQuantile`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ce8d71795c9e401ab3a4c38276fb3d7b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
