This horizontal bar chart displays population figures for the ten most populous countries, with bars extending from left to right on a linear scale. The visualization is built with D3.js (v5), using `d3.csv` to load the dataset, `scaleLinear` for the x-axis, `scaleBand` for the categorical y-axis, and `axisLeft`/`axisBottom` for the axes. Population values are multiplied by 1,000 during data preprocessing, and bars are rendered as SVG rectangles in steelblue.
