{"version":"1.0","type":"rich","title":"GDP United States","description":"This bar chart displays the quarterly gross domestic product of the United States over time, with each bar representing a data point from a JSON dataset loaded via `d3.json`. The visualization uses a simple SVG-based bar chart created with `select('svg')`, where bar heights correspond to GDP values. The code relies on D3 v5’s core selection and data-joining methods, though the actual rendering logic is incomplete, as the dataset fetching and bar generation are stubbed out in comments.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d9ed4e9156b74153ad08f24037509d31?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
