Automatically creating a functional block diagram from ansi c code

Question

Does anyone know a tool that can create "function diagrams" from any code?

By “functional diagram” I mean a diagram that is an overview of files, functions, and their relationships. I imagine that this is something like a circus chart.

For instance. if there is the following code:

//MyProgram.c
int main(int argc, char** argv)
{
    Foo();
    Bar();
    return 0;
}

//Slave.h
void Foo();
void Bar();

The diagram will look something like this:

Does he have an official name? Dependency chart, maybe?

I looked at Doxygen a bit. But he clearly states that: Doxygen has built-in support for generating inheritance diagrams for C ++ classes. Same thing with many UML tools. I have no classes. Although my c files may be close.

It is strange that these diagrams do not actually exist. It seems to me that people, such as embedded programmers, ansi c, low level, hw, etc., will love them.
