A bar chart displays population figures for ten countries, using horizontal bars whose lengths encode the numeric values from a CSV dataset. The chart is built with D3 v5, loading data via `d3.csv` and rendering SVG elements through `select` and `append`. The visualization centers a simple rectangular bar in the middle of a 960-by-500 pixel SVG canvas, styled with an Ubuntu font and white background. The code focuses on a single bar rather than a full categorical comparison, leaving the remaining chart structure incomplete.
