This scatter plot visualizes the Iris dataset, mapping petal length and width for each flower sample while coloring points by species. Using D3 v6, the chart renders as SVG circles, with dimensions computed from a linear scale on both axes. The code loads CSV data via `d3.csv`, parses numeric fields, and applies a custom scale for the shapes’ `rx` and `ry` attributes, though the actual circle radius is fixed. Axis components are generated with `axisLeft` and `axisBottom`, and the visualization fills the full browser window.
