This scatter plot visualizes the Iris dataset, showing the relationship between petal length and petal width, with data points colored by species (setosa, versicolor, virginica). It loads CSV data from a GitHub repository using D3 v6’s `csv` function, then employs `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` to map coordinates and render axes. The SVG circles are positioned via `cx` and `cy`, with colors assigned through a switch statement. The chart fills the browser window using `window.innerWidth` and `window.innerHeight`, with axis labels displayed in green.
