This scatter plot visualizes the Iris dataset, showing the relationship between petal length and petal width for three iris species (setosa, versicolor, and virginica), with each species represented by a distinct color. The visualization uses D3.js v6 to load the data from a GitHub-hosted CSV, scale linearly based on data extents, and render circles in SVG. It displays axes with tick labels and axis titles, and positions the marks according to the petal dimensions, highlighting species-based color encoding.
