An interactive scatter plot visualizes the Iris dataset, allowing users to compare any pair of four floral measurements via two dropdown menus. The plot depicts all 150 specimens as colored circles, with light pink, green, and orange distinguishing the three iris species through a custom color legend. Built with D3 v5, the visualization uses `csv()` to load data, `scaleLinear()` for axes, and `axisBottom()`/`axisLeft()` for grid lines. Animated transitions animate circles from the chart’s center to their plotted positions after each axis selection. SVG rendering displays the chart and dropdown menus.
