This scatter plot visualizes the Iris dataset, showing petal length against sepal width for three species of Iris flowers. A color legend identifies each species with a distinct color, and hovering over a data point displays its value in a tooltip. The visualization is built with React and D3 v5, relying on `scaleLinear` for the axes, `scaleOrdinal` for the color mapping, and `extent` for the data domain. The chart uses SVG rendering with custom components for axes, marks, and the legend.
