This interactive scatter plot visualizes the Iris dataset, allowing users to explore relationships between four measured attributes (sepal length/width, petal length/width) across three flower species. Dropdown menus dynamically change the x- and y-axis variables, while a color legend distinguishes species using a d3.scaleOrdinal with categorical colors. Built with React and d3.v5, the SVG-based visualization renders axes via custom components, circles with tooltips, and a color legend that updates proportionally to the selected attributes. Data is loaded asynchronously from a CSV file using d3.csv.
