This interactive scatter plot displays the Auto MPG dataset from the UCI Machine Learning Repository, letting users compare any two numeric car attributes (like horsepower, weight, or acceleration) by selecting columns via dropdown menus. Implemented with D3 v5, the visualization uses `scaleLinear`, `extent`, and `axisBottom`/`axisLeft` to build axes, while dropdown menus are created with a custom `dropdownMenu` function that appends `<select>` and `<option>` elements. Points animate into position with a 2-second transition, and the SVG rendering includes red semi-transparent circles.
