This example displays Fisher’s iris dataset as a scatter plot mapping sepal length against petal length. Points are colored and shaped by species, using D3’s `scaleOrdinal` and `symbolsFill` to assign distinct symbols. A legend, built with D3’s `symbol` generator, identifies each species. The plot features axes labeled with Sepal Length and Petal Length, generated via `axisLeft` and `axisBottom`, and loads data from a CSV using `csvParse`.
