This example demonstrates the basic structure of an HTML page as a starting point for loading and parsing CSV data with D3. It shows a minimal, empty document with a title and a body, ready to receive JavaScript code. The visualization relies on the HTML file itself and does not yet include any D3 functions, data loading, or parsing. The code uses a standard HTML `<!DOCTYPE html>` declaration and a head section to define the page title, but no external libraries or data sources are present.
