This interactive scatter plot displays the Iris flower dataset, allowing users to explore relationships between four measurements (sepal length, sepal width, petal length, and petal width). Two dropdown menus built with ReactDropdown let viewers select which attribute appears on each axis. The visualization uses React state management to track selections and update the scales and marks accordingly. D3 utilities such as `csv`, `scaleLinear`, `extent`, and `max` handle data loading and scaling, while custom React components render SVG axes and circles as marks.
