This example visualizes the structure and organization of wget commands from a text-based guide, categorizing them into groups like downloading single files, mirroring websites, handling restricted content, and retrieving file details. The visualization uses a tree layout with collapsible nodes, rendered via D3.js, to display command categories and their associated examples. Each leaf node represents a specific wget command with its option flags, while the hierarchy reflects the logical grouping from the source document. The data is parsed directly from the original text, preserving the command syntax and descriptions. The interface allows users to expand and collapse branches to explore the command reference interactively.
