This example displays a horizontal bar chart of country populations using D3.js v6 and SVG, with data loaded from a CSV file via `d3.csv`. It shows the population of each country scaled linearly on the x-axis and categorically on the y-axis using `scaleLinear` and `scaleBand`. The chart renders axes with `axisLeft` and `axisBottom`, and applies a fixed top, right, bottom, and left margin to position the plot area. Bars are appended as SVG rectangles with steelblue fill, and the code uses `select`, `max`, and `csv` from the D3 module.
