This example displays a minimal "Hello world" message inside a plain HTML page, demonstrating the simplest possible setup for a web-based visualization. The page uses no external libraries or JavaScript APIs, relying solely on the browser’s native HTML rendering to display the static text. The source code consists of a single `index.html` file with a basic document structure, including a `<head>` and `<body>` section. This fork of a hello-world template serves as a starting point for adding more complex data visualizations, but currently only renders the literal text "Hello world" without any interactive or dynamic elements.
