This interactive scatter plot visualizes the Iris Dataset, letting users independently choose which of the four flower measurements to plot on the X and Y axes using React dropdown menus. Species are distinguished by color through a d3.scaleOrdinal mapping to a three-color palette. The visualization is rendered as SVG using React components, with axes and marks generated via d3.scaleLinear, d3.extent, and custom React components for the bottom and left axes, alongside d3.csv for data loading and d3.format for tick labels.
