This bar chart displays 2018 state population data from datausa.com. It uses D3 v5 with an SVG rendering approach, mapping population values to horizontal bar lengths against state labels. The code employs `d3.csv`, `scaleLinear`, and `scaleBand` to process the data and position the bars, with `axisLeft` and `axisBottom` generating the chart’s axes. Each state’s population is represented by a steel-blue rectangle, sorted alphabetically along the vertical axis.
