What is the best way to illustrate website navigation?

The best way to illustrate website navigation is through a clear and intuitive visual sitemap or wireframe. This should include a hierarchical structure that outlines main categories and subcategories, allowing users to understand how to access different sections easily. Additionally, using interactive prototypes can demonstrate the flow and functionality of navigation elements, ensuring that users can quickly grasp the site's layout. Incorporating consistent design elements, such as menus and breadcrumbs, further enhances usability.
