{"version":"1.0","type":"rich","title":"Covid","description":"This example presents a world map visualization of COVID-19 case data, coloring each country based on its total reported cases. The map is rendered using React and D3, with a Natural Earth projection via `d3.geoPath` and `d3.geoNaturalEarth1`. Data is loaded from a remote CSV file using the Fetch API and parsed with `d3.csvParse`. A sequential color scale using `d3.scaleSequential` and `d3.interpolateReds` maps case counts to fill colors, while country boundaries are drawn as SVG paths with white strokes. The visualization dynamically updates when new data is fetched.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7e959fee5f2441a888bda006e2fd6526?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
