This interactive scatter plot visualizes the Iris dataset, displaying sepal length against sepal width with points colored by species. Hovering over the color legend highlights the corresponding species by increasing the opacity of its data points while fading others. The visualization uses React with D3 v7 scales and SVG rendering, including custom AxisBottom, AxisLeft, Marks, and ColorLegend components. The color legend employs mouse events to trigger the hover state, with the ordinal color scale mapping three distinct species to individual colors.
