This interactive scatter plot visualizes the Auto MPG dataset from the UCI Machine Learning Repository, displaying car attributes as circles. Users select which data columns to map to the X and Y axes using dropdown menus, with the chart animating transitions between selections. Built with D3 v5, the visualization uses `d3.csv` for data loading, `d3.scaleLinear` for axes, `d3.axisLeft` and `d3.axisBottom` for ticks, and SVG rendering. The custom `dropdownMenu` component handles menu creation, while the scatter plot animates circle positions over two seconds.
