+#### **GraphViz Visualizations Generator for the codebase and crates/modules.**
 
 This tool generates graph diagrams for the whole codebase or separate exact crates/modules.
 It can generate graphs of dependencies for modules in a crate, and graphs for code internals inside modules of a crate (package), visualizing interrelations of types, traits (abstract types, interfaces), and functions/methods to them.
 
+It can be used for documentation, onboarding new team-mates, and for analyzing the points of future architectural improvements.
