This interactive scatter plot explores the UCI Auto MPG dataset, letting users dynamically choose which numeric columns (e.g., horsepower, weight, acceleration) map to the X and Y axes via dropdown menus. Built with d3.v5, it renders an SVG with animated circle transitions. The implementation uses `scaleLinear`, `extent`, and `axisBottom`/`axisLeft` for scaling and axes, while a custom `dropdownMenu` module handles the select elements, updating the plot on change.
