This scatter plot visualizes the classic Iris dataset, displaying petal length against sepal width for three iris species. Each circle is colored by species using a d3.scaleOrdinal with a categorical color range, and includes a native SVG <title> tooltip. The visualization is built with React and D3 v5, using d3.scaleLinear scales with extent-based domains and d3.csv for data loading. Axis components are custom-built with React, rendering SVG tick marks and labels with formatted tick values.
