This horizontal bar chart ranks the top 20 countries by total reported COVID-19 deaths, using a steel-blue fill for each bar. The x-axis is labeled "Deaths" and uses a custom tick formatter that abbreviates large numbers (e.g., "1.13M"), while the y-axis lists country names. Built with D3 v5, the visualization uses `scaleLinear` for the numeric axis, `scaleBand` for the categorical country axis, and `axisBottom`/`axisLeft` for grid lines and labels. Data is loaded from a local CSV file.
