This interactive scatter plot visualizes the Iris dataset, comparing sepal length and width across three species of iris flowers. The visualization uses d3.scaleLinear and d3.scaleOrdinal to map data points, with hover interactions that highlight the selected species while fading others. Points are rendered as large circles with BBC-inspired color theming, and a custom legend provides interactive filtering. The chart displays titles, axis labels, and source attribution, all styled through CSS and configured via a centralized config object. The code also employs a ResizeObserver for responsive rendering.
