This bar chart displays the populations of the top 10 most populous countries, using a horizontal layout with country names on the y-axis and population values on the x-axis. The visualization is built with D3 v5, specifically using `scaleLinear` for the x-axis, `scaleBand` for the categorical y-axis, and `axisLeft`/`axisBottom` for the axes. Data is loaded from a CSV file and multiplied by 1000 to reflect actual population figures. The SVG rendering uses steelblue rectangles, with margins and padding handled through D3’s scale and transform methods.
