How to view AST in a graph

Hello, my frineds
Does ``glslang`` can print a AST as graph?

some thing like ``.dot`` file, and use ``graphviz`` to view what the AST really is?

or can we use other tools to view a AST in a graph?

The issue names no files, tests, or entry points. Start by checking glslang's available AST inspection interfaces and whether Graphviz or .dot output is documented; done would be a documented way to view an AST as a graph, or a clear statement that no such support exists.
