A horizontal bar chart displays population counts for six countries, with bars scaled linearly and labeled by country name. The visualization loads data from a CSV file and renders it as SVG rectangles with steelblue fill. Built with D3 v5, it uses `d3.csv`, `scaleLinear`, `scaleBand`, `axisLeft`, and `axisBottom` to construct the chart, appending axes and bars to a grouped SVG element within a 960×500 viewport.
