C5 — Print a graph

Turn any eagle graph into a picture: the same layout and renderers draw a C++ cpu::Graph and a Python eagle.Graph.

Time: ~2 min · Runs on: CPU (pure C++, no CUDA) · You need: C2

    const eagle::graph::Description d = eagle::graph::describe(g);
    const eagle::graph::Layout lay    = eagle::graph::layout(d);
    std::cout << eagle::graph::ascii(d, lay);

describe read the four nodes and their dependencies; layout put the two siblings on one stage; ascii drew the boxes. The full story, including Mermaid, DOT and finding edges from raw memory ranges, is Seeing a graph from C++: eagle/graph.
