Author or serialize a flow as a diagram

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.

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();
  1. Write the diagram

    Node contracts live in %%ax directives; labeled edges become branches and loops.

  2. Compile with flow()

    A string argument to flow() compiles the dialect into a runnable flow.

  3. Render it back

    String(wf) returns the diagram, so flow(String(wf)) round-trips the program.

Set OPENAI_APIKEY in your environment before running provider-backed code.
