This scatter plot visualizes the Iris dataset, mapping petal length and width as the primary x and y coordinates while encoding sepal dimensions as data attributes for each point. Circles are colored by iris species—setosa, versicolor, and virginica—using a switch statement. Built with D3 v6, the visualization uses `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` to construct scales and axes, rendering SVG circles with data joined via `selectAll` and `join`. The CSV data is loaded asynchronously from a GitHub source, with a full-viewport responsive layout.
