This example presents a scatter plot of the classic Iris dataset, loaded from a GitHub-hosted CSV using D3.js’s `d3.csv`. The visualization is rendered as an SVG element that fills the entire browser window, with dimensions set to the viewport’s height and width via `window.innerHeight` and `window.innerWidth`. The code parses the dataset’s four numeric columns (sepal length, sepal width, petal length, petal width) into integers using the `parseRow` function, though it does not yet map these fields to visual positions or draw any points. Instead, it establishes the SVG canvas and logs the parsed data to the console, leaving the plotting logic incomplete.
