This bar chart displays the populations of the ten most populous countries, with circles representing each nation and a linear scale mapping population values. The chart uses D3 v7 to load CSV data, scaleLinear for the x-axis, and scalePoint for categorical country positioning on the y-axis. Axes are rendered via axisBottom and axisLeft, with grid lines drawn through tick sizing. The visualization includes a title and axis labels, while styling is handled through external CSS.
