This interactive scatter plot explores relationships between attributes of cars from the UCI Auto MPG dataset. Two dropdown menus let the user select which columns to plot on the x and y axes. Built with D3 v5, it uses the `scaleLinear` and `axisLeft`/`axisBottom` APIs to render axes, while a custom `dropDown` module handles menu creation. Points animate smoothly between states using D3's `.transition().delay()` methods.
