This bar chart displays the population of the top 10 most populous countries in 2018 using a horizontal layout. The visualization loads data from a CSV file and renders as SVG, with bars colored in steelblue and a formatted x-axis using `d3.scaleLinear`, `d3.scaleBand`, and `d3.axisBottom` with tick formatting to abbreviate large numbers. The chart includes a title, axis label, and uses `d3.csv` for data loading and `d3.max` to determine the scale domain.
