This interactive scatter plot visualizes the Iris flower dataset, allowing users to compare any two numeric attributes by selecting them from dropdown menus. The chart renders circles for each data point using SVG, with axes and tick marks generated from D3 scales and formatting. Written in React with D3 v5, the visualization updates the x and y scales and re-renders marks whenever the user changes the selected attributes. The Iris dataset is loaded as CSV and parsed with d3.csv.
