This interactive scatterplot visualizes the Iris dataset, letting users explore relationships between sepal and petal measurements across three flower species. Each point is colored by species using d3.scaleOrdinal, with dropdown menus powered by ReactDropdown to switch which quantitative attributes appear on the x and y axes. The chart renders as SVG with React components, using d3.scaleLinear for axes and d3.extent to compute domains dynamically. Data loads asynchronously via d3.csv, and the interface includes labeled axes and hover tooltips showing species names.
