This horizontal bar chart displays the populations of the world's most populous countries, using D3 v7 to render the visualization as an SVG. It reads data from a CSV file and scales the population values by a factor of 1000. The chart employs `scaleLinear` for the x-axis, `scaleBand` for the y-axis country categories, and uses the `axisLeft` and `axisBottom` functions to draw the axes, with steelblue rectangles for bars.
