This scatter plot visualizes the Iris dataset, displaying petal length and width for individual flowers. The circles are color-coded by species: skyblue for setosa, lightgreen for versicolor, and orange for virginica. Using D3 v6, the example loads data from a remote CSV via `d3.csv`, parses the numeric columns, and maps them to SVG circles using `d3.scaleLinear` for the x and y axes. It also incorporates sepal dimensions into the `rx` and `ry` attributes, making each point an ellipse. The chart renders axis labels with `d3.axisLeft` and `d3.axisBottom`, and uses D3's `select` and `join` APIs for efficient SVG element creation.
