A Go library that takes a pointer to an arbitrary data structure and generates a Graphviz DOT file, producing a visual graph diagram of the structure's memory layout and relationships. It serves as a debugging aid, offering a clearer alternative to pretty-printing complex nested or linked data structures.

Use cases

• visualize linked lists, trees, and graphs in Go for debugging
• understand complex nested struct relationships at a glance
• generate DOT diagrams from Go data structures
• debug pointer-heavy data structures that are hard to read when printed
• teach or document how a Go data structure is laid out in memory

When to choose

• You are debugging intricate Go data structures like linked lists, trees, or graphs
• Pretty-printed output is too hard to follow for nested or pointer-heavy structures
• You want a quick visual diagram without writing custom visualization code
• You already have Graphviz installed and want a simple library call to generate diagrams

When to avoid

• You need a general-purpose Go profiler or memory analyzer rather than a structure visualizer
• Your project does not use Go
• You cannot or do not want to install Graphviz to render the output
• You need a maintained tool with recent updates and active support
