This fork of a scatter plot with color legend visualizes the Iris Dataset, plotting petal length against sepal width. Each of the 150 data points appears as a colored circle, with the three iris species distinguished by an ordinal color scale. The chart uses React components for rendering SVG marks and axes, while D3’s `scaleLinear` and `scaleOrdinal` handle coordinate and color mappings. A color legend generated from the scale’s domain identifies each species.
