{"version":"1.0","type":"rich","title":"Covid-19 global cases","description":"This choropleth map visualizes global COVID-19 cases by country, using a color scale based on economic grouping. The map renders with D3’s `geoNaturalEarth1` projection and `geoPath`, allowing zoom interactions via `d3.zoom`. A clickable ordinal color legend filters highlighted countries, with dimming for non-selected regions. Data is loaded from a CSV and TopoJSON using `d3.csv` and `d3.json`. The visualization uses SVG elements and applies hover effects through CSS.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/babd4b7256624438a44775fa6a540658?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
