This scatter plot visualizes the Iris dataset, comparing sepal length and width across three species using a BBC-inspired color palette. Built with D3 v7, it uses `scaleLinear` for axes, `scaleOrdinal` for categorical coloring, and interactive legend hover effects that fade non-selected species. The visualization loads data via `d3.csv` from a GitHub gist and includes a responsive `ResizeObserver` for dynamic resizing.
