A horizontal bar chart displays total COVID-19 deaths for 20 countries, with red bars ranked by country name on the y-axis and a linear death count scale on the x-axis. It loads CSV data via `d3.csv`, parses and filters the dataset, and renders SVG rectangles sized with `scaleBand` and `scaleLinear`. The React component manages state with hooks and uses D3’s axis utilities for gridlines and tick labels.
