This visualization displays the Iris dataset as a scatter plot of sepal length against sepal width, with each flower represented by a circle. Built with React and D3 v5, it uses `d3.scaleLinear` for axes and `d3.extent` to set domains, while `d3.csv` loads data from a GitHub-hosted CSV. The SVG rendering includes custom axis components and circle marks with tooltips showing the sepal length value.
