This interactive scatter plot explores the Auto MPG dataset from the UCI Machine Learning Repository, displaying car attributes like horsepower and weight. Users dynamically reassign axes via dropdown menus, triggering a two-second animated transition where circles grow and reposition using D3’s `transition()` and `delay()`. Built with D3 v5, the SVG visualization uses `scaleLinear`, `axisBottom`, and `axisLeft` for axes, with all numerical columns parsed from CSV. The example demonstrates reusable menu components and animated updates for exploring multivariate relationships.
