This example shows a horizontal bar chart of the ten most populous countries, with bar widths proportional to each nation’s population (displayed in thousands). The visualization is built with D3 v5, using `scaleLinear` for the x-axis and `scaleBand` for the y-axis, rendering rectangles as SVG elements. Data is loaded from a CSV file via `d3.csv`, with population values parsed and multiplied by 1000 before the chart is drawn.
