This example uses a scatter plot to visualize the Iris dataset, displaying petal length and petal width on the axes while coloring each point by species (setosa, versicolor, virginica). The D3 v6 code loads CSV data via the `csv` function, maps sepal and petal measurements using `scaleLinear` and `extent`, and renders the plot with SVG circles. It creates axes using `axisLeft` and `axisBottom` and adds data-driven colors, providing a clear comparison of species clusters in the flower measurements.
