This interactive visualization explores the Iris dataset, showing how the relationship between two selected attributes (such as petal length and sepal width) varies across species. Color distinguishes species, with a legend that highlights one species at a time while fading others on hover. Built with React and D3.js v7, it uses `scaleOrdinal` for coloring and `scaleLinear` for both axes, rendering circular marks as SVG. The code also utilizes D3’s `csv` parser for data loading and `format` for axis label abbreviations.
