This example uses a scatter plot to visualize the Iris dataset, displaying sepal length against petal length. Points are color-coded, with distinct shapes distinguishing the three Iris species, supported by a legend for reference. Built with D3 v7, the visualization uses the `select()` and `join()` APIs to efficiently manage SVG elements, while `scaleLinear` and `scaleOrdinal` handle positional and shape encodings. The chart loads data from a remote CSV file and includes axis labels and tick marks for readability.
