This archived example displays the raw contents of a CSV file containing the classic Iris dataset, showing parsed tabular data as formatted JSON in a `<pre>` element. It demonstrates lazy-loading and state management with D3 v7, using `d3.csvParse` to convert fetched text into an array of objects, then coercing numeric columns with unary plus operators. The visualization is minimal, focusing on the data-loading pipeline rather than a graphical representation, with a state machine tracking undefined, `'LOADING'`, and loaded data states.
