This scatter plot visualizes the Iris dataset, showing the relationship between sepal length and petal length. Each point is shaped according to the iris species—setosa, versicolor, or virginica—with a legend mapping shapes to species. Built with D3 v7, the code uses `scaleLinear` and `scaleOrdinal` to map data to positions and shapes, while `axisLeft` and `axisBottom` render the axes. Data is loaded via `fetch` and parsed with `csvParse`.
