This scatter plot displays car data from the UCI Machine Learning Repository’s Auto MPG dataset, allowing users to choose which columns map to the X and Y axes via dropdown menus. The visualization uses D3 v5’s `scaleLinear`, `axisBottom`, and `axisLeft` for axes, and animates circles with `transition().delay()`. Rendering is SVG-based, with the `dropdownMenu` module handling the select elements and `scatterPlot` managing the chart layout and labels.
