This example visualizes the classic Iris Dataset as a scatter plot, showing petal length versus sepal length for 150 flowers across three species. The visualization uses D3 v7 to load the CSV data via `csvParse`, and the `scatterPlot` function constructs linear scales with `scaleLinear` and `extent` to map data values to screen positions. Each data point is rendered as a circle using D3’s data join pattern, though the plot omits axes, focusing purely on the spatial distribution of the points. The chart fills the entire browser window dynamically.
