This example displays a horizontal bar chart of the top 10 countries by population, using data from a CSV file. It shows the population values as bar lengths, with country names on the y-axis and a linear population scale on the x-axis. The visualization is implemented with D3 v6, using `select`, `csv`, `scaleLinear`, `scaleBand`, `axisLeft`, and `axisBottom` to load the data, set up scales, render SVG rectangles, and draw axes. Rendering is performed via SVG elements appended to a pre-defined `<svg>` container.
