This interactive scatter plot explores relationships between car attributes from the UCI Auto MPG dataset. Two dropdown menus let users select which numeric columns map to the X and Y axes, using a reusable `dropdownMenu` module. The `scatterPlot` module renders SVG circles with D3 scales and axes, animating points into place via `transition().duration(2000)` with staggered delays. Data is loaded with `d3.csv` and parsed as numbers before rendering.
