This bar chart displays the populations of the world’s ten most populous countries, with each bar’s length proportional to its population. The chart uses a linear scale for the x-axis and a band scale for the categorical y-axis, drawing the bars as SVG rectangles via the D3.js `select`, `scaleLinear`, `scaleBand`, and `axisBottom` APIs. Population values are parsed from a local CSV file, and axis ticks are formatted using D3’s `format` to abbreviate large numbers, while the chart’s title and axis labels are added as SVG text elements.
