This interactive scatter plot visualizes the Iris dataset, allowing users to explore relationships between sepal and petal dimensions by selecting different measurements for the X and Y axes via dropdown menus. The D3.js visualization uses `csv` to load data and `scaleLinear` with `extent` for axes, while circles animate their positions with `transition` when axes change. The scatterPlot module uses `selectAll` and `join` for rendering SVG circles and axes, with an interactive menu system built with `dispatch` for change events.
