This scatter plot visualizes the Iris dataset, mapping petal length and petal width on the x- and y-axes while coloring points by species (setosa, versicolor, and virginica) using skyblue, lightgreen, and orange. It also encodes sepal length and width into the circle attributes `rx` and `ry`, creating elliptical markers. Built with D3 v6, the code loads CSV data via `d3.csv`, uses `scaleLinear` and `extent` for scales, and renders SVG circles with `selectAll` and `join`. Axis labels are added via `axisLeft` and `axisBottom`.
