This example presents a scatter plot of the Fisher Iris dataset, mapping sepal length to the x-axis and petal length to the y-axis, with each species distinguished by a unique fill symbol. The visualization includes labeled axes and a shape legend to identify species. Implemented with D3 v7, it uses `scaleLinear` and `scaleOrdinal` for scaling, `symbol()` for symbol generation, and custom modules for drawing axes and legend, fetching the data from a GitHub-hosted CSV file.
