The bar chart displays population estimates for ten countries, using horizontal bars to compare values from China down to Mexico. The visualization encodes population on the x-axis and country names on the y-axis, with steelblue rectangles sized proportionally to each nation’s population. It uses D3’s `scaleLinear`, `scaleBand`, `axisLeft`, and `axisBottom` to construct the scales and axes, while the data is loaded from a CSV file and rendered as SVG. The chart’s width and height are read directly from the SVG element’s attributes.
