This interactive scatter plot of the Iris dataset allows users to explore relationships between flower measurements by selecting different attributes for the x and y axes via dropdown menus. Hovering over the color legend highlights points of a selected species while fading others, with an opacity transition applied to non-hovered marks. The visualization is built with React, d3.scaleLinear and d3.scaleOrdinal for scales, and renders SVG circles with tooltips. The data is loaded as CSV and parsed using d3.csv.
