This interactive scatter plot displays automobile data from the UCI Machine Learning Repository’s Auto MPG dataset. Users select which numerical columns map to the X and Y axes via dropdown menus, implemented with a custom `dropdownMenu` module. The visualization uses `d3.scaleLinear` for axes, `axisBottom` and `axisLeft` for ticks, and animates circle positions with `transition().duration(2000)`. Updates re-render the SVG, preserving axis labels and tick marks while smoothly transitioning data points to new coordinates.
