You can write a whole flow as a mermaid flowchart and compile it by passing the string to flow(). Any flow renders back with String(flow), so the diagram and the program stay in sync.

Unit example (nearest native match)
See the idea in context
std::string mermaid = R"(flowchart TD
%%ax classify: request:string -> route:class "support, sales"
classify{route})";
auto program = axllm::flow(mermaid);
std::cout << program.str();
Write the diagram
Node contracts live in %%ax directives; labeled edges become branches and loops.
Compile with flow()
A string argument to flow() compiles the dialect into a runnable flow.
Render it back
String(wf) returns the diagram, so flow(String(wf)) round-trips the program.
