This example displays a horizontal bar chart of the top ten most populous countries, using population data loaded from a CSV file. The chart ranks countries by population, with bars extending along a linear scale. The visualization is rendered as an SVG using D3.js v5, employing `scaleLinear`, `scaleBand`, `axisLeft`, and `axisBottom` for scales and axes, while `csv` loads the data and `format` customizes tick labels.
