This interactive scatter plot visualizes the Iris dataset, allowing users to select which flower measurements appear on the x and y axes via dropdown menus. The plot uses React dropdowns to control the axes, with d3.scaleLinear for positioning and d3.scaleOrdinal for species-based coloring. Hovering over the color legend highlights points of a selected species, using React’s useState to manage the hovered value, while SVG circles render each data point with tooltips.
