This visualization displays the top 10 most populous countries as a horizontal bar chart using SVG rendering. It loads population data from a CSV file via `d3.csv`, scales the values with `d3.scaleLinear` and `d3.scaleBand`, and formats axis ticks with `d3.format`. The chart uses `d3.axisLeft` and `d3.axisBottom` for axes, with custom labels and a steelblue fill for bars.
