A horizontal bar chart displays the ten most populous countries, with populations scaled in thousands from a CSV file. The chart uses D3 v5 to build linear and band scales and axis generators, then customizes the axes by removing domain lines and default grid lines, adding a rotated x-axis label, and formatting tick labels to abbreviate large numbers (e.g., "1.42B"). The SVG rendering includes a title and styled tick marks, axis labels, and bars in steel blue.
