This interactive scatterplot visualizes the height and width of Iris flower organs, allowing users to toggle between sepal and petal measurements via a dropdown menu. The SVG chart uses D3 v7’s `scaleLinear`, `axisLeft`, and `axisBottom` to map dimensions, with points colored by Iris species (setosa, versicolor, virginica). Data comes from the `iris.csv` dataset. The visualization highlights how petal measurements cluster more distinctly by species compared to sepals, revealing the dataset’s classic separation pattern.
