This scatter plot visualizes the Iris dataset, displaying sepal length against sepal width, with each of the three iris species distinguished by a unique color from a d3.scaleOrdinal range. Built with React and rendered as SVG, the chart uses d3.scaleLinear for both axes and d3.format for tick labels. Data is loaded asynchronously via d3.csv. A native SVG `<title>` element provides simple tooltips on each circle.
