A scatter plot of the Iris dataset shows petal length against sepal length for three flower species, with each species color-coded in green, indigo, or red. Users click through animated transitions that rotate the x-axis among four measured variables every two seconds, using D3 scales, axes, and circle elements. The visualization also renders an additional set of circles with rectangular corner radii based on sepal measurements, and loads data asynchronously via D3’s `csv` parser.
