This scatter plot visualizes the Iris dataset, mapping sepal length on the x-axis and sepal width on the y-axis. Each circle represents a flower sample, with axis labels and tick marks rendered using React components that call d3.scaleLinear, d3.extent, and d3.max. The SVG circles include a title element for tooltips, showing the sepal length value on hover. The code uses d3.csv for data loading and d3.format for axis tick formatting.
