This interactive scatter plot visualizes the Auto MPG dataset from the UCI Machine Learning Repository, showing relationships between car attributes. Two dropdown menus let users select which columns map to the X and Y axes, with axes, labels, and points updating accordingly. The visualization uses D3 v5’s `scaleLinear`, `axisBottom`, `axisLeft`, and `select` APIs, along with a reusable `dropdownMenu` component. Points animate via `transition().duration(2000)` with staggered delays, rendered as semi-transparent red SVG circles with grid lines.
