This fork visualizes the Iris dataset, showing how sepal length and width vary across species. The scatter plot encodes species with distinct colors from the BBC theme, and includes an interactive legend that fades non-hovered points. It uses `d3.scaleLinear`, `d3.scaleOrdinal`, `d3.axisBottom`, `d3.axisLeft`, and `d3.csv` to load life from a GitHub gist.
