This bar chart displays the population of ten countries in 2020, using data from Worldometers, with China leading at over 1.4 billion. The visualization uses the D3 v5 library to bind the CSV data to SVG rectangles, scaling the bar lengths with `scaleLinear` and positioning them with `scaleBand`. Axis labels are generated via `axisLeft` and `axisBottom`, while the chart’s margins are set explicitly to accommodate the country names. The bars are styled with a steelblue fill.
