An interactive scatter plot of the Iris dataset displays petal length against sepal length, with each of the 150 flowers colored by species (setosa, versicolor, virginica). The visualization uses D3 v7 with a linear scale for both axes, an ordinal color scale for species categories, and an SVG-based legend. Data loads asynchronously via `d3.csv` from a GitHub gist, with axes rendered using `d3.axisBottom` and `d3.axisLeft`. The plot adapts to the browser window size, showing clear species clustering patterns.
