{"version":"1.0","type":"rich","title":"Athlete Data from 2024 Boston Marathon","description":"This visualization displays athlete data from the 2024 Boston Marathon, showing the raw dataset as a JSON-formatted text dump within a `<pre>` element. It uses D3 v7’s `csvParse` to load and parse the data, converting numeric string fields like `first_half`, `finish`, and `percent_change` into numbers for analysis. The visualization updates reactively via a `setState` function, triggering a re-render of the container with the newly fetched data. It demonstrates a minimal data-loading workflow without any chart or graphical encoding.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b9ae8477752749068128f0fa52d08ba9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
