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.
