This example demonstrates VizHub version 3’s “Hello World” template, showing a minimal main function that renders the text “Hello World!” and a paragraph directly into a container DIV. It illustrates the simplified runtime setup, where the exported main function receives a container element and uses string interpolation to set inline CSS font sizes. The code highlights the interactive widget system, where holding the Alt key and dragging a number in the editor—like the fontSize constant—enables continuous hot reloading, providing immediate visual feedback without refreshing the page.
