This scatter plot visualizes the Iris dataset, showing each flower's petal length on the x-axis and petal width on the y-axis. Each point is colored by species (skyblue for setosa, lightgreen for versicolor, orange for virginica), and a legend identifies these color groupings. Built with D3 v6, the visualization uses `d3.csv` to load data, `d3.scaleLinear` for axis scaling, and `d3.axisLeft`/`d3.axisBottom` to render axes. The code also loads sepal dimensions into the dataset, though these are not visually encoded.
