This scatter plot visualizes the Iris dataset, displaying sepal length on the x-axis and sepal width on the y-axis for three species of iris flowers. The visualization uses D3's `scaleLinear` function to map data values to pixel coordinates, with circles representing individual samples. The `xAxis` and `yAxis` functions from D3 render the axes, while custom label functions from the `@curran/axis-labels` library add axis titles. A light gray rectangle highlights the plotting area, and semi-transparent circles reveal overlapping data points. The example demonstrates a reusable plotting pattern that can be adapted to other datasets.
