{"version":"1.0","type":"rich","title":"Untitled","description":"This example demonstrates basic SVG shape construction on a static HTML page, combining a diagonal line, a rounded rectangle, and a vibrant green circle within a translated group. The visualization labels the shapes as \"Rectangle\" and \"Circle\" using monospaced text, while a larger title announces \"d3.js 学习 Day01\" (D3.js Learning Day 01). The code relies on raw SVG elements—`line`, `rect`, `circle`, `g`, and `text`—styled with inline CSS and attributes like `transform`, `fill`, and `stroke`. No JavaScript libraries are imported; it is a pure HTML/CSS/SVG composition.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/922e999624b246e98cc806e3988d21b7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
