This interactive scatter plot visualizes the Iris dataset, showing the relationship between petal width and sepal length across three iris species. Each point represents a flower, colored by species using a categorical color scale. The visualization is built with D3.js, using `scaleLinear` and `scaleOrdinal` for scaling, `axisBottom` and `axisLeft` for axes, and `csv` to load data from a GitHub gist. The plot fills the window and includes labeled axes for petal width and sepal length.
