This example demonstrates basic JavaScript syntax and concepts through a series of commented-out examples, including variables, arithmetic, functions, arrow functions, and object literals. The active code defines an arrow function `person` that returns an object with `first` and `last` properties, then logs the result to the console. It uses an SVG element for structure but relies entirely on the browser's developer console for output. The visualization is rendered without any external libraries, focusing purely on core programming fundamentals rather than data-driven graphics.
