This example shows a minimal p5.js sketch as a starting point for the VizHub V3 Runtime Environment, which supports hot reloading and interactive widgets. The code draws five horizontal bars on a 400×400 canvas, with each bar’s width randomized via the `random()` function and redrawn once per second using `frameRate(1)`. It uses p5.js’s `setup()`, `draw()`, `createCanvas()`, and `rect()` APIs, and loads the library from a CDN in a simple HTML file.
