This scatter plot visualizes the classic Iris dataset, mapping petal length and width for each sample point. The visualization encodes the three Iris species—setosa, versicolor, and virginica—using distinct colors (skyblue, lightgreen, and orange), with each circle’s radius fixed at 5 pixels. Built with D3 v6, it loads the dataset via `d3.csv`, scales both axes with `d3.scaleLinear`, and renders axes using `d3.axisLeft` and `d3.axisBottom`. The SVG output displays labeled axes for petal length and width, with data points positioned using the `selectAll` and `join` pattern.
