This scatter plot visualizes the Auto MPG dataset from the UCI Machine Learning Repository, displaying car attributes as circles. Users can select which data columns map to the X and Y axes through two dropdown menus. The visualization uses D3 v5’s `scaleLinear`, `axisLeft`, `axisBottom`, and `extent` APIs, with SVG rendering. Selecting a new column triggers an animated transition where circles move to their new positions over one second, using `transition().duration(1000).delay((d, i) => i * 10)` for a staggered effect. The plot is updated via a custom `dropdownMenu` module and `scatterPlot` function.
