This bar chart displays the populations of the ten most populous countries, with the United States at roughly 327 million and China leading at over 1.4 billion. Values are read from a CSV file and scaled using `d3.scaleLinear` and `d3.scaleBand`, while axes are generated with `axisLeft` and `axisBottom`. The chart uses D3 v5 to render SVG rectangles, with each bar’s height set by the band scale and its width proportional to population.
