This example demonstrates the VizHub V3 Runtime Environment’s “Hello World” template, displaying the text “Hello World!” centered on the page with a large, adjustable font size. It uses plain HTML and inline CSS via a template literal in JavaScript, with an interactive widget that lets the user alt-drag the numeric value to change the font size. The rendering is handled entirely through the container’s innerHTML, with no external libraries or data sources. This serves as a minimal starting point to explore the runtime’s hot-reloading and interactive parameter editing.
