This bar chart compares house prices across different house sizes, with teal bars representing each category and rotated labels on the x-axis for readability. The visualization uses D3 v7 to load CSV data from a GitHub gist, scales the data with `d3.scaleBand` and `d3.scaleLinear`, and renders the chart as SVG. Axes are generated using `d3.axisBottom` and `d3.axisLeft`, while the plot area measures 900 by 380 pixels with margins. The code directly binds the data to rectangle elements for each bar.
