This example shows the raw contents of a CSV file containing religious demographic data by country, displayed as a JSON-formatted string within a pre element. The visualization loads the Iris Dataset’s CSV structure—though the actual data lists religion percentages—and parses it using `d3.csvParse`. The current state is rendered via D3’s `select` and `join` methods, with asynchronous fetching triggered on initial load. The code demonstrates a simple state management pattern, where `setState` re-renders the visualization after data arrives.
