This bar chart displays population counts for ten countries, using horizontal bars encoded by length, with data loaded from a CSV file. The SVG visualization relies on D3 v5’s `select` and `csv` methods to fetch and parse the data, then appends `rect` elements to the chart. Population values are converted from thousands to raw numbers via unary plus multiplication. The chart’s styling is defined in an external stylesheet, with axes and labels positioned using D3’s scale and axis components, though the code snippet only shows the initial rendering setup.
