SVG Fundamentals
This example demonstrates the VizHub V3 runtime environment, showing a "Hello World" message with adjustable font size. It serves as a blank slate starting point, illustrating the platform's core features: a `main` function exported from `index.js` that receives a container and options object, eliminating the need for an `index.html` file. The code uses interactive widgets that enable continuous hot reloading, allowing properties like font size to be modified in real-time via Alt-drag. The visualization renders text directly into the container using plain HTML and CSS, with the state management system initialized as an empty object.
