This React scatterplot visualizes the Iris dataset, plotting sepal length against sepal width with tooltips displaying exact values on hover. The SVG-based chart includes labeled axes and a title. Built with React 18 and D3.js, it uses `scaleLinear` from d3-scale for coordinate mapping, `extent` for domain calculation, and `csv` for data loading. The visualization is composed of reusable components for axes, marks, and the overall chart group, with the dataset fetched from a GitHub-hosted CSV file.
