This example displays U.S. housing sales volumes as a static bar chart, with regions on the x-axis and sales on the y-axis. It uses the D3.js library (specifically `d3.csv` for data loading, `d3.scaleBand`, `d3.scaleLinear`, and `d3.axisBottom`/`d3.axisLeft` for scales and axes) to render SVG rectangles. The chart is populated from a remote CSV file sourced from a GitHub gist, styled with steelblue bars that turn orange on hover, and includes labeled axes for clarity.
