This scatter plot displays automobile data from the UCI Machine Learning Repository’s Auto MPG dataset, with users selecting X and Y axes via dropdown menus. Built with D3 v5, it uses `scaleLinear`, `extent`, `axisLeft`, `axisBottom`, and `transition().duration()` for animated circle rendering. The `dropdownMenu` function binds `<select>` elements to column options, while `scatterPlot` handles SVG axes, labels, and data point transitions.
