{"version":"1.0","type":"rich","title":"Hello VizHub","description":"This example demonstrates a minimalist \"Hello VizHub\" message rendered as large, centered text on a dark blue background. It shows how a basic D3.js selection and text assignment can integrate with ES6 module imports and external CSS styling. The code uses `d3.select` to target the `#message` div and set its content from an imported `message` constant, while the page loads D3 v5 from a CDN and applies Ubuntu font styling via Google Fonts. The example highlights the structure of a VizHub project with separate HTML, JavaScript, and stylesheet files.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
