{"version":"1.0","type":"rich","title":"Choropleth Map","description":"This choropleth map visualizes the global distribution of COVID-19 cases using a red and green color scheme, with each country’s fill color indicating the presence of cases on a specific date. The map is rendered with SVG using D3’s `geoNaturalEarth1` projection and `geoPath` for geographic outlines, while `zoom` enables interactive panning. Data is loaded from a CSV file and merged with TopoJSON world geometry via `loadAndProcessData`, and a custom `colorLegend` component displays the categorical scale.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4dd431803a5e4bb1bfabc9ed3767fc6d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
