{"version":"1.0","type":"rich","title":"Choropleth Map","description":"A choropleth map colors countries according to their economy, using a categorical color scale and an interactive legend to filter by income group. Built with D3 v5, it projects geographic data from the world-atlas topojson using `geoNaturalEarth1` and renders each country as an SVG path via `geoPath`. The legend, generated through a separate module, allows clicking to highlight or dim countries by color value, while a zoom interaction adjusts the projection transform.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/dfb5301609e64c809be5ed2f9b767dc4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
