This visualization displays population data for several countries as a set of vertical bars, with each country labeled on the x-axis and its population represented by the bar height on the y-axis. The bars are rendered in steelblue on an SVG canvas. The implementation uses D3 v5, leveraging `d3.csv` to load the data, `scaleBand` for the x-axis positioning, and `scaleLinear` for the y-axis scaling. Axis components are generated using `axisLeft` and `axisBottom`.
