This scatterplot visualizes the Iris dataset, plotting petal length against sepal width, loaded from a CSV file via GitHub Gist. Written in React and rendered as SVG with D3.v5, the code uses `scaleLinear` for axes, `extent` for domain calculation, and `format` for tick labels. The visualization includes styled axis tick marks, labels, and circular marks with tooltip titles showing the x-axis value. D3’s `csv` function handles data loading, while React components like `AxisBottom`, `AxisLeft`, and `Marks` structure the chart.
