This example shows a horizontal bar chart of country populations, with countries arranged along the y-axis and population counts scaled along the x-axis. The visualization uses d3.csv to load data, d3.scaleLinear and d3.scaleBand to map values to positions, and SVG rectangles for rendering. Custom margins are applied by translating a group element, demonstrating basic axis setup without displaying axes. The chart highlights relative population differences among the ten most populous countries.
