This bar chart displays the population of the ten most populated countries in the world, using data from the UN World Population Prospects. It renders the countries on the y-axis with horizontal bars scaled by population via `d3.scaleLinear` and `d3.scaleBand`. The SVG visualization is built with d3 v5, using `d3.csv` to load the data, `d3.axisLeft` and `d3.axisBottom` for labeling, and includes a steelblue fill for each bar.
