This scatter plot displays 392 cars from the UCI Machine Learning repository, with dropdown menus letting users select which numeric attributes to compare on the x and y axes. The visualization uses d3.csv for data loading, d3.scaleLinear, d3.extent, and d3.axisLeft/axisBottom for scales and axes, while a custom dropdownMenu module handles the interactive selection. Circles animate into position over two seconds via d3.transition with staggered delays, rendered as SVG with semi-transparent red fill.
