This scatter plot visualizes the Iris dataset, mapping petal length and width to the x and y axes while coloring each point by species. The code uses D3 v6 APIs including `csv`, `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` to load and render the data as SVG circles. Although the markup includes redundant `rx` and `ry` attributes, the circles maintain a fixed radius, producing a straightforward categorical color encoding of the three flower types.
