{"version":"1.0","type":"rich","title":"question4.1","description":"This example demonstrates a minimal D3.js visualization that displays a centered text message, “Hello VizHub!”, on a web page. It shows how to import D3 functions and local ES6 modules, with the text styled via CSS. The code uses `d3.select` to target the HTML element and sets its text content, while the message string comes from a separate local module. The visualization loads D3 version 5.16.0 from UNPKG and runs entirely in the browser.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4d38fd8e629e433c87fb73ff53660d72?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
