This example demonstrates loading an external CSV dataset—the Iris Dataset—and displaying its contents as formatted JSON in the browser. Using D3 v5’s `csv` function, it fetches the data asynchronously and, upon resolution, appends a `<pre>` element to the body with `JSON.stringify` to render the parsed array with indentation. The code imports `select` and `csv` directly from the D3 module, relying on Promises to handle the data load.
