This interactive scatter plot, built with React and D3 v5, visualizes the Iris Dataset, plotting petal length against sepal width. An ordinal color scale distinguishes the three iris species, and a color legend with mouse hover effects enhances exploration. When a species is hovered, the chart fades all non-matching data points using an opacity transition, allowing for focused comparison. The visualization uses SVG rendering and D3 scales for axes and color encoding.
