This example demonstrates the foundational “Hello World” pattern for the VizHub V3 Runtime Environment, showing how to render simple text-based content into a container. The code uses vanilla JavaScript and the DOM API to set the `innerHTML` of the container, with a static `fontSize` variable of 221 pixels applied via an inline style. It highlights the environment’s hot-reloading capability, where interactive widgets appear during development, and serves as a minimal starting point for building more complex visualization projects.
