This scatter plot displays relationships between pairs of columns in the Auto MPG dataset from the UCI Machine Learning Repository. Two dropdown menus let users choose which columns to plot on the x and y axes. The visualization uses D3 v5, with `scaleLinear` for axes, `axisLeft` and `axisBottom` for ticks, and animated circle transitions via `transition().duration(2000).delay()`. The SVG chart redraws its axes and labels whenever a menu selection changes.
