This visualization displays a horizontal bar chart of the top 10 countries with the highest COVID-19 death counts, with country names on the y-axis and death totals on the x-axis. The chart uses React for component structure and D3 v5 modules including `scaleLinear`, `scaleBand`, and `csv` for data loading, rendering as SVG rectangles. Data is sourced from a public CSV file fetched asynchronously, and the bars are styled with a uniform purple fill against a dashed-border title.
