{"version":"1.0","type":"rich","title":"Choropleth Map with Interactive Filtering","description":"This interactive choropleth map shows world countries colored by name, with a clickable legend that filters the map to highlight a selected country while dimming others. The visualization uses D3 v5 with `geoNaturalEarth1` projection and `geoPath` for rendering countries, and `d3.zoom` for pan and zoom. Data combines CSV attributes with TopoJSON country boundaries, while the ordinal color scale uses `schemeSpectral`. Clicking a legend item toggles the filter, adjusting opacity and stroke width for highlighted countries.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e5f9ddfb7fed46c98f0752c1698ee659?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
