This interactive scatter plot visualizes Fisher’s Iris dataset, comparing sepal length and sepal width across three iris species. The visualization uses D3 v7’s `scaleLinear` and `scaleOrdinal` to map data values to positions and colors, with points rendered as SVG circles. Hovering over a legend item highlights that species’ points while fading others, implemented through D3’s `.on()` event handlers and state management. The chart includes styled axes, titles, and a legend, with color schemes defined in a BBC-inspired theme.
