This visualization combines a bar chart and line chart to compare the average price and average area of homes across six Texas cities. The steel-blue bars represent average price, while the red line and overlaid circles show the average area, using dual left and right y-axes. Created with D3 v7, the graphic uses `scaleBand`, `scaleLinear`, `axisBottom`, `axisLeft`, `axisRight`, and `line` to encode the data, all rendered as SVG elements on a dark background with a manually drawn legend.
