This interactive scatter plot visualizes the Auto MPG dataset, letting users explore relationships between numeric vehicle attributes. Two dropdown menus, built with a custom D3 module, select which columns are plotted on the x- and y-axes. The chart uses D3 v5 scales, axes, and SVG circles that animate from the center to their positions with a staggered delay, while gridlines and axis labels update dynamically. The code is structured as reusable ES6 modules for the menu and plot.
