This visualization displays the population of the top 10 most populous countries as horizontal bars, sorted by descending value. It uses D3 v5 with SVG rendering, loading data from a CSV file and scaling populations (normalized by thousands) via `scaleLinear` and `scaleBand`. Axes are generated with `axisBottom` and `axisLeft`, with the y-axis stripped of its domain line and ticks. The code formats tick labels using D3's `format` function, converting billions to ‘B’ suffix.
