{"version":"1.0","type":"rich","title":"HTML Starter","description":"This example demonstrates a minimal HTML page that uses D3 v6 to render a single blue rectangle onto an SVG canvas within a React-based project structure. The page includes embedded CSS that centers and enlarges body text, while a script appends an SVG element with fixed 500x500 dimensions, then selects and appends a rectangle with hardcoded position and size attributes. The code also logs a message to the browser console and serves as a bare-bones starting point for visualization development.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a8671b906de8466697e7c0c65fa43b0a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
