This scatter plot visualizes the Iris Dataset, showing petal length against sepal width for three iris species. A color legend identifies each species, and hovering over a legend item highlights the corresponding points while fading others. The visualization uses React with D3 v5 for scales and SVG rendering, employing `scaleLinear` for axes, `scaleOrdinal` for colors, and custom React components for axes, marks, and the interactive legend.
