{"version":"1.0","type":"rich","title":"Fork of Fork of Choropleth Map with Interactive Filtering","description":"This choropleth map colors world countries by their economy group, using a spectral color scale. Users can click any color legend swatch to isolate that economy category, while all other countries fade to low opacity. Hovering a country highlights it in red. The map renders with `d3.geoPath`, updated via a D3 zoom interaction, while `d3.scaleOrdinal` and `d3.schemeSpectral` drive the categorical colors. Data comes from the `world-atlas` package, joined with TSV income-group values.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a4a2117da9424f33864e7effd3328538?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
