This interactive scatter plot uses D3.js to visualize the Auto MPG dataset from the UCI Machine Learning Repository, showing relationships between car attributes like horsepower, weight, and acceleration. Two dropdown menus allow users to select which columns map to the X and Y axes using the custom `dropdownMenu` function. The scatter plot renders as an SVG with animated transitions, using D3's `scaleLinear`, `axisLeft`, and `axisBottom` APIs to display axes and data points.
