SVG Fundamentals
This example demonstrates the foundational elements of SVG-based data visualization, starting with a plain HTML page that renders a centered message using CSS styling. The code, written in React, introduces the structure of an SVG document and shows how HTML and CSS can be combined to present text content. It serves as a minimal starter for understanding how to build more complex visualizations, with the message “Hello HTML!” displayed using a large font size. The example relies on standard web APIs such as the Document Object Model and CSS for layout and styling, without yet incorporating JavaScript libraries like D3 or simulation functions.
