This bar chart displays confirmed COVID-19 case counts for ten countries, with the United States leading at over one million cases. The visualization uses D3 v5’s `scaleLinear` and `scaleBand` to map case numbers to horizontal bars and country names to vertical positions, rendering as SVG. Axes are generated with `axisBottom` and `axisLeft`, with tick formatting via `format('.3s')`. Data is loaded from a CSV file, and styling is applied through external CSS, including green-filled rectangles and custom title labels.
