{"version":"1.0","type":"rich","title":"HTML Starter","description":"This example shows a plain HTML page with the text “Hello HTML!” displayed in large, centered type. It serves as a minimal starter template for D3-based projects, demonstrating how to structure a basic document without any JavaScript logic or data binding. The page uses standard CSS styling within a `<style>` block to set the font size and text alignment, and a single `<div>` element with the class `message` to hold the content. No external libraries are loaded, making this a pure HTML and CSS demonstration.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/791a9e95e98944d989abfd0cb5b50a3d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
