This scatter plot visualizes the Iris dataset, displaying sepal length on the x-axis and petal length on the y-axis. Each point is colored according to the species of iris flower, with a color legend labeling the three categories. The visualization uses D3.js version 7.6.1, leveraging the library's selection join operation, linear and ordinal scales, and the ColorBrewer categorical color scheme. Custom modules handle axis generation and the color legend, while data is loaded from a CSV file.
