This scatter plot visualizes the Iris dataset, displaying petal length on the x-axis and petal width on the y-axis. Each circle represents a flower, colored by species: lightblue for setosa, lightpink for versicolor, and yellow for virginica. The code uses D3 v6 APIs including `csv`, `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` to load data, create scales, and render axes. The visualization also incorporates sepal measurements as radius properties, though the circles maintain a fixed radius of 5 pixels.
