This horizontal bar chart displays the populations of the ten most populous countries, using D3 v5 to map values to bar widths via `d3.scaleLinear` and `d3.scaleBand`. The SVG rendering includes gridlines, axis labels, and a title, with data loaded from a CSV file. Axis construction relies on `d3.axisLeft` and `d3.axisBottom`, while numeric tick labels are formatted using `d3.format`. The visualization is generated entirely client-side through D3’s data-join pattern.
