This example displays a bar chart of total COVID-19 deaths for fourteen countries, with a steelblue bar per nation and a numeric label above each bar. The chart uses D3 v7’s `scaleBand` and `scaleLinear` to map countries and death counts, while `d3.axisBottom` and `d3.axisLeft` render the axes. Interactive tooltips appear on mouseover, showing the country name and formatted death total. The visualization is rendered as an SVG, with data hard-coded in the script.
