This example shows a scatter plot of the Iris Dataset, mapping petal length on the x-axis and sepal width on the y-axis. Built with React and D3 v5, it renders SVG circles using the `scaleLinear` and `extent` functions to position marks. The axes are custom components that generate ticks and grid lines. Data is loaded asynchronously via D3’s `csv` function from a GitHub gist, with numeric coercion applied in the row parsing callback.
