This interactive scatter plot displays relationships between attributes of cars from the UCI Machine Learning Repository’s Auto MPG dataset. Users select which data columns map to the x and y axes via dropdown menus, triggering smooth circle transitions over two seconds. The visualization uses d3.csv for data loading, d3.scaleLinear and d3.extent for scales, d3.axisLeft and axisBottom for axes, and d3.transition with a staggered delay for animations.
