{"version":"1.0","type":"rich","title":"Sean Thornton MA Unemployment","description":"This example displays the monthly unemployment rate in Massachusetts from 1976 to 2003, with data sourced from the Federal Reserve Economic Data (FRED) series MAUR. The visualization loads a CSV file via `fetch` and parses it with `d3.csvParse`, then renders the raw data as text in a `<pre>` element using D3’s `select` and data join. The code relies on D3 v7 and a simple state management pattern to handle the asynchronous loading process.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d6281a6651804f15a856a440d03c1fbc?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
