{"version":"1.0","type":"rich","title":"Chloropleath Map","description":"This example displays a world choropleth map coloring countries by economy type, using a natural Earth projection and an ordinal color scale. It loads geographic data from the World Atlas TopoJSON and TSV files, rendering SVG paths with `d3.geoPath` and TopoJSON’s `feature`. A zoom behavior via `d3.zoom` pans and scales the map, while a custom color legend built with SVG circles and text shows the categorical values. The map also includes tooltips via appended `title` elements, with a dark blue sphere background and black country strokes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7e9f15cb9e034bfeadd8719a5c67af7e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
