An interactive scatter plot of the classic mtcars dataset lets viewers compare any two of four car attributes—mpg, cyl, disp, and hp—by selecting each axis from a dropdown menu. Built with React and D3 v5, it renders SVG circles whose positions are calculated with `scaleLinear` and `extent`, and axes are drawn using the custom `AxisBottom` and `AxisLeft` components. The plot displays values with a `siFormat` tick label and includes hover tooltips via SVG `<title>` elements.
