This scatter plot visualizes the Iris dataset, displaying sepal length against petal length for three flower species. Each species is represented by a distinct shape—circles, squares, or triangles—as defined by a d3.symbol() generator, allowing for visual differentiation without relying on color. The plot includes labeled axes and a legend created with a custom shapeLegend module. The visualization is built using D3 v7, renders as an SVG, and loads its data from a local CSV file.
