This interactive scatter plot visualizes the Iris dataset, allowing users to explore relationships between sepal and petal measurements across three flower species. The visualization displays points colored by species, with dropdown menus to select which measurements appear on the x and y axes, and maintains a color legend that highlights points of a selected species while dimming others. Built with React and d3.js using the `scaleLinear` and `scaleOrdinal` functions, the plot renders as SVG with custom axes and mark components.
