This horizontal bar chart visualizes the populations of the top ten most populous countries using D3 v5, with data loaded from a local CSV file. It renders as an SVG, using the `scaleLinear`, `scaleBand`, `axisLeft`, and `axisBottom` APIs to construct the plot. The chart displays a title, an x-axis labeled "Population" with tick formatting that abbreviates large numbers (e.g., converting G to B), and steelblue bars representing each country's population, where values are multiplied by 1000 from the source data.
