This area chart shows average rent in Dallas, plotting minimum life expectancy against dog breed names. The visualization combines a smooth orange area fill with a black line overlay, using D3 v5’s `area` and `line` generators with `curveBasis` for interpolation. It loads CSV data from a GitHub gist, applies `scaleLinear` for both axes, and uses `axisLeft` and `axisBottom` with custom tick formatting. The chart is rendered as SVG within a React project, with axis labels and gridlines styled via CSS classes.
