This scatter plot visualizes the Iris dataset, showing petal length against sepal width with points colored by species. The code uses React, D3 v6, and SVG rendering, with `scaleLinear` for axes, `scaleOrdinal` for categorical colors, and `csv` to load data from a GitHub gist. Custom `AxisBottom` and `AxisLeft` components generate ticks, while the `Marks` component draws circles with tooltips.
