This interactive scatter plot visualizes the Auto MPG dataset from the UCI Machine Learning Repository, displaying car attributes such as horsepower, weight, and acceleration. Users select which columns to map to the X and Y axes via dropdown menus built with the custom `dropdownMenu` function. The visualization uses d3.v5 with `scaleLinear`, `axisBottom`, and `axisLeft`, rendering SVG circles with animated transitions (`transition().duration(2000)`) that move points to their new positions when axes change.
