This interactive scatter plot from the Auto MPG dataset lets users explore relationships between car attributes via dropdown menus. Built with D3 v5, it renders animated SVG circles that transition smoothly when the X or Y axis column is changed. The visualization uses `scaleLinear`, `axisLeft`, and `axisBottom` for axes, with `dropdownMenu` handling user selection. A color legend with clickable swatches filters data points. Data loads from a CSV via `csv()` and is processed in `loadAndProcessData`.
