{"version":"1.0","type":"rich","title":"Choropleth Map Project","description":"This choropleth map visualizes global economic classifications by coloring each country according to a categorical scale derived from the `economy` property in the World Atlas dataset. The map uses a natural Earth projection and renders as SVG with D3’s `geoPath` and `geoNaturalEarth1`. Country boundaries are drawn with thin strokes, and hovering over a country turns it gray while a tooltip displays the country name and its economy group. A custom color legend, built with `scaleOrdinal` and `schemeSpectral`, appears in the lower-left corner. The map supports zooming through D3’s zoom event handler.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/14a70442e124420f9fe84ab00ef0ba1c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
