This interactive scatter plot displays automobile characteristics from the UCI Auto MPG dataset. Dropdown menus allow users to select which numerical columns (e.g., horsepower, weight, acceleration) map to the X and Y axes. The chart uses D3 v5's `scaleLinear`, `axisLeft`, `axisBottom`, and `transition().duration(2000).delay()` to animate points when axes change, rendering as SVG with circles and axis labels.
