This interactive scatter plot visualizes the Auto MPG dataset from the UCI Machine Learning Repository, showing relationships between car attributes. Users select which columns to plot on the X and Y axes via dropdown menus. The visualization is built with D3 v5, using `scaleLinear`, `axisLeft`, and `axisBottom` for axes, while `transition().duration()` animates circle positions when the data mapping changes. The SVG rendering includes axis labels and semi-transparent red circles.
