This interactive scatter plot uses React and D3 to visualize the Iris flower dataset. Users explore relationships between sepal and petal measurements by selecting attributes for the x and y axes from dropdown menus. The plot encodes species using color, and hovering over the color legend highlights points of that species while fading others. The SVG visualization builds axes with D3 scales, formats tick labels with `d3.format`, and links the dataset via a custom React hook.
