This example shows US housing sales by state as a static bar chart, with each bar’s height representing the number of sales and a rotated x-axis label for each state. The chart is rendered as an SVG using D3 v6, leveraging `d3.csv` to load data from a GitHub Gist, `d3.scaleBand` and `d3.scaleLinear` for scales, and `d3.axisBottom` and `d3.axisLeft` for axes. The visualization includes a title and uses a steelblue fill for the bars.
