{"version":"1.0","type":"rich","title":"Choropleth Map with Interactive Filtering","description":"A choropleth map colored by economy category uses color-coding to show global economic groupings, with a legend that filters countries by clicking a category or hovering to highlight. Built with D3.js v5, it projects geographic data using `d3.geoNaturalEarth1` and `d3.geoPath`, while an ordinal `scaleOrdinal` with `schemeSpectral` drives the fill colors. The map loads world atlas TopoJSON and TSV data, and the legend’s click handler toggles the selected value to adjust country opacity, with a zoom interaction via `d3.zoom`. Hovering a country turns it red, and tooltips display the country name and color value.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ed51e93a6aa9408095b5af555bddf772?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
