{"version":"1.0","type":"rich","title":"Fork of D3 Course Code Along - Choropleth Map","description":"This visualization presents a world map using a discrete color scale to categorize countries by income group, with a legend and hover effects identifying countries. The map is generated with `d3.geoPath` and a `geoNaturalEarth1` projection, converting TopoJSON world atlas data. Animated color transitions in the legend are handled via `.transition().duration(1000)`. The underlying population data is loaded from a TSV file, while the map geometry comes from the world-atlas package.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1857cca8becd40619ec7bdd673289d6e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
