This horizontal bar chart displays the population of the ten most populous countries, sorted alphabetically by country name. The visualization encodes population values as bar lengths along a linear scale, using the country names as categorical labels. The chart renders as an SVG using d3’s `scaleLinear`, `scaleBand`, `axisLeft`, and `axisBottom` APIs, with population tick labels formatted in a compact “B” suffix style. Data comes from the bundled `data.csv` file, and styling is applied via a linked CSS file.
