{"version":"1.0","type":"rich","title":"Circles on a Map","description":"This visualization displays a choropleth map of global economies, with countries colored by their economic classification using a spectral ordinal scale. An interactive color legend allows viewers to click a category, highlighting matching countries and dimming others, while pan and zoom controls enable map exploration. The map uses D3 v5 with `geoNaturalEarth1` projection, `geoPath`, and `zoom` for navigation, while `scaleOrdinal` with `schemeSpectral` drives the color encoding. Data is loaded via TopoJSON and TSV from the world-atlas package, rendered as SVG paths with hover effects and tooltips showing country names and values.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/bed9f54d46eb47aeb66e951288df698d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
