This interactive scatterplot visualizes the Iris flower dataset, letting users explore relationships between sepal and petal measurements via dropdown menus that select the x and y axes. The chart displays points colored by species through a D3 scaleOrdinal color legend. Built with React and D3 v5, it renders as SVG using d3.scaleLinear for axes, d3.extent for domains, and custom React components for axes, marks, and the color legend.
