This scatter plot visualizes the Iris dataset by mapping petal length and petal width to point positions. Each point represents an iris flower, and its color indicates the species (pink for setosa, red for versicolor, green for virginica). The visualization is built using D3 v6 and rendered as SVG, with axes created using `axisLeft` and `axisBottom`. The code loads data from a CSV file, uses `scaleLinear` for coordinate mapping, and applies `selectAll` with a `join` operation to create the circle marks.
