{"version":"1.0","type":"rich","title":"Hello VizHub","description":"This example displays a large, centered “Hello VizHub!” message in a light gray sans-serif font against a dark gray background. It serves as a minimal demonstration of a basic D3.js v5 setup within the VizHub environment. The code uses `d3.select` to target the `#message` div and sets its text content with a string imported from a separate ES6 module. Styling is applied via an external CSS file that imports the Ubuntu font from Google Fonts, with the body configured for centered alignment and a large font size.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8ffc326caa3a48fb98b1ed3842d978a8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
