{"version":"1.0","type":"rich","title":"Fields of Transparency","description":"An interactive dendrogram visualizes the hierarchical structure of political ad data from Facebook and Snapchat, with branches and node labels depicting platform-specific fields like ad creation time, demographics, and spending. The visualization uses a D3 tree layout with horizontal link paths and zoom functionality for navigation, rendered as SVG on a black background with red connections. Font sizes decrease with each hierarchical level, and the data comes from a JSON file containing nested objects representing each platform’s advertising data schema.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e8ce4857e1374a21a689d2b2cd53f67b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
