This interactive scatter plot lets users explore the relationship between any two columns of the automotive dataset by selecting axes from dropdown menus. Built with D3 v5, it renders SVG circles that animate from the center to their positions using `transition()`. The code uses `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` for scales and axes, with data loaded from a CSV file. The dropdown menus are generated using a reusable `dropdownMenu` component that binds options to a native `<select>` element.
