This bar chart displays the populations of the world’s ten most populous countries, with each bar’s length proportional to its value. The visualization uses D3 v5 with SVG rendering, employing `scaleLinear` for the x-axis and `scaleBand` for the categorical y-axis. Data is loaded from a CSV file via `d3.csv`, and axes are generated using `axisLeft` and `axisBottom`. The chart applies a fixed margin layout and styles the rectangles with steelblue fill.
