{"version":"1.0","type":"rich","title":"copy graph","description":"This interactive choropleth map visualizes the spread of COVID-19 across African countries, using color to encode categories of total confirmed cases. A slider allows switching between three different data files representing different time periods. The visualization uses D3 v5 with `geoMercator` projection, `geoPath` for rendering, and TopoJSON world atlas data merged with CSV case data. Hovering highlights individual countries, while a color legend with circles explains the ordinal color scale based on `schemeSpectral`. Pan and zoom functionality is enabled via D3's zoom behavior.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a1d5a3406090438d864cf4260a16a7eb?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
