{"version":"1.0","type":"rich","title":"Campaign Data","description":"This example renders a full-screen “Hello VizHub!” message in large, bright Ubuntu type on a dark navy background. The code demonstrates basic D3.js DOM selection using `d3.select` to set the text content of a div, alongside an ES6 module export for the message string. It uses D3 v5, loaded from a CDN, with styling defined in an external CSS file and a minimal HTML skeleton. The visualization’s purpose is purely illustrative, showcasing component separation and library integration.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7d04ffb0fe7946e59d2cb70f30393575?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
