This interactive scatter plot from the D3 v5 gallery displays car attributes from the UCI Auto MPG dataset, with dropdown menus controlling the x- and y-axis variables. Users select columns like horsepower or weight to update the axes, and points animate to their new positions over two seconds using chained transition and delay methods. The visualization uses d3.scaleLinear, d3.axisBottom, d3.axisLeft, and SVG circles with opacity, while custom dropdown menu functions bind change events to trigger re-renders.
