This example shows a horizontal bar graph of population by country using data from a CSV file. The bars are rendered as SVG rectangles in steel blue, with countries on the y-axis and population values on the x-axis. The code uses `d3.csv` to load the data, `d3.scaleLinear` for the x-scale, `d3.scaleBand` for the y-scale, and `d3.axisLeft` and `d3.axisBottom` to draw the axes. Population values are multiplied by 1000 before rendering.
