This visualization shows the top 10 countries by cumulative COVID-19 deaths, using horizontal bars scaled by total deaths. It renders an SVG bar chart with d3.scaleLinear for the x-axis and d3.scaleBand for the y-axis, styled with custom CSS. The data comes from a CSV file sourced from Worldometers, and the chart includes a formatted x-axis with d3.format and labels for the chart title and axis. The code uses D3 v6 within a React framework.
