This scatter plot visualizes the classic Iris dataset, mapping petal length on the x-axis and sepal width on the y-axis. Each flower is represented as a colored circle, with species distinguished by a d3.scaleOrdinal color scale. The chart is built as a React component using reusable axis and mark components, with d3.csv for data loading and d3.scaleLinear for positioning. Axis ticks and labels are generated procedurally, and SVG tooltips display exact petal length values on hover.
