This example demonstrates loading and parsing comma-separated value (CSV) data using the D3.js library. It displays information about Iris flower petal and sepal measurements in a styled HTML page with an accompanying SVG illustration. The code uses `d3.csv` to fetch and parse the data, then renders it into a `<pre>` element. The visualization combines CSS styling, an external image, and custom SVG shapes to create an educational interface for learning data loading workflows.
