This interactive scatter plot visualizes the Auto MPG dataset from the UCI Machine Learning Repository. Two dropdown menus let the user select which numeric columns (such as horsepower, weight, or acceleration) map to the x- and y-axes. The code uses the d3.csv and d3.scaleLinear APIs for data loading and scaling, with d3.axisBottom and d3.axisLeft for axis rendering. Points animate into position via d3 transitions with staggered delays, and axis labels update to reflect the selected columns.
