{"version":"1.0","type":"rich","title":"learning","description":"This example displays a simple D3.js visualization inside an SVG: a single red circle centered within a message div. It demonstrates core VizHub workflows, including loading D3 from UNPKG via a script tag, importing D3 functions like `select` in ES6 modules, and importing a local `message` constant from `myMessage.js`. The code uses D3 v5 and renders static SVG markup without data binding or interactive behavior.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/147b2e4ed8b64394a7745110a2719860?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
