This interactive scatter plot visualizes Fisher's Iris dataset, comparing sepal length and sepal width across three iris species. Points are color-coded by species, and hovering over legend items highlights the corresponding points while fading others. The visualization is built with D3.js v7, using `scaleLinear` and `scaleOrdinal` for axes and colors, plus `axisBottom` and `axisLeft` for tick marks. Styling follows BBC Graphics conventions with custom color palettes defined in the theme.
