{"version":"1.0","type":"rich","title":"Fork of Choropleth Map with Interactive Filtering","description":"This choropleth map displays country-level economic classifications using a natural Earth projection, with a color-coded legend that filters the map when clicked. The visualization uses D3 v5’s `geoNaturalEarth1` and `geoPath` to render geographic features from TopoJSON world-atlas data, while `scaleOrdinal` and `schemeSpectral` assign colors. Clicking a legend item dims non-matching countries and highlights the selected category; hovering reveals country names and values via SVG `<title>` elements. Pan and zoom are enabled through the `zoom` behavior.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9bd3330dcb0446a983b3aa64a89ddd78?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
