{"version":"1.0","type":"rich","title":"HTML Starter","description":"This example demonstrates a minimal HTML page that displays the text “Practice: Make a face with D3.js!” centered on the screen. The page uses plain HTML with embedded CSS in a `<style>` tag to set the body font size to 10em and center the text. It serves as a bare-bones starter template, with no JavaScript or external libraries included. The rendering relies solely on the browser’s default HTML and CSS handling, providing a blank canvas for users to add their own D3.js code.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4eb4ecab5e4d41418ab58c6d6fb79d6a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
