This example visualizes the annual GDP of Worcester, MA from 2001 to 2023 using data from the Federal Reserve Economic Data (FRED) series NGMP49340. It displays the raw numerical values as a formatted JSON list within the page. The code uses D3 v7’s `csvParse` to load the data from a CSV file and relies on the `select` and `join` methods to bind and render the data. The visualization state manages asynchronous loading, initially showing `"LOADING"` before the parsed data appears.
