This interactive scatter plot visualizes car attributes from the UCI Auto MPG dataset, with dropdown menus letting users choose which columns to map to the x- and y-axes. The visualization uses d3.scaleLinear and d3.axisBottom/axisLeft to render axes, while circles animate into position via d3 transitions. The code implements a custom dropdownMenu component and a scatterPlot function that updates axes and data points when menu selections change, rendering as SVG.
