This scatter plot visualizes the Iris dataset, showing petal length against sepal width for three iris species. Each point is colored by species using a d3.scaleOrdinal with a categorical color range. The visualization uses React components for rendering SVG elements, with d3.scaleLinear for the x and y axes. Axes are constructed manually from d3 scale ticks, and hover tooltips display the petal length value via SVG title elements.
