This interactive scatter plot visualizes the Auto MPG dataset from the UCI Machine Learning Repository, displaying car attributes such as horsepower, weight, and acceleration. Two dropdown menus let users select which columns map to the X and Y axes, with the plot transitioning smoothly when selections change. Built with D3 v5, the visualization uses d3.csv for data loading, d3.scaleLinear and d3.axisBottom/Left for scales and axes, and d3.transition for animated circle repositioning. Red semi-transparent circles render in SVG, with axis labels updating to reflect the chosen variables.
