This dashboard visualizes COVID-19 summary data from the covid19api.com API. Users load global totals or per-country figures, which are rendered as animated bar charts using D3 v5 scales, axes, and transitions within React components. The interface includes a navigation menu built with D3 selections, a country selector for filtering individual records, and SVG canvases for chart display. Data updates trigger React re-renders alongside D3 append and merge operations.
