This scatterplot displays the Iris dataset, plotting petal length against sepal width for individual flowers. Built with React and rendered as an SVG, it uses D3’s `scaleLinear` with `extent` and `nice` to compute axes, which are drawn by custom `AxisBottom` and `AxisLeft` components. The `Marks` component maps each data point to a circle with a `<title>` tooltip, and data is loaded asynchronously via D3’s `csv` from a gist URL. The visualization includes axis labels and a custom tick format, but does not encode species or other dimensions.
