This example presents a static SVG bar chart titled "Javascript 101," rendered with a single white bar outlined in black. It primarily serves as a canvas for commented JavaScript code snippets that demonstrate core programming concepts, including function definitions, object creation, array manipulation with `map` and `splice`, and a simple data storage system using `updateLevelData` and `getLevelData`. The visualization shows how text and basic shapes can be combined with code annotations, using a fixed 960x500 SVG canvas and styled text at 72px.
