This bar chart shows total COVID-19 cases for 14 countries, with values labeled above each bar. It uses d3.scaleBand for the x-axis, d3.scaleLinear for the y-axis, and d3.axisBottom/d3.axisLeft to render the axes. Bars are drawn as SVG rectangles with a steelblue fill, and case numbers are formatted with toLocaleString. The chart includes a title and uses the d3.selectAll pattern to bind data to elements.
