DAGVIZ

DAGVIZ offers a "git log"-like visualization for DAGs represented in networkx.

Installation

DAGVIZ can be installed with pip:

pip install git+https://github.com/ELIFE-ASU/dagviz.git

Documentation

Documentation is available at https://wimyedema.github.io/dagviz/.

Usage

DAGVIZ relies on networkx for the representation and manipulation of the DAG. An SVG file can be generated as follows:

    import dagviz
    import networkx as nx
    # Create the DAG
    G = nx.DiGraph()
    for i in range(5):
        G.add_node(f"n{i}")
    G.add_edge(f"n0", f"n1")
    G.add_edge(f"n0", f"n2")
    G.add_edge(f"n0", f"n4")
    G.add_edge(f"n1", f"n3")
    G.add_edge(f"n2", f"n3")
    G.add_edge(f"n3", f"n4")
    # Create an SVG as a string
    r = dagviz.render_svg(G)
    with open("simple.svg", "wt") as fs:
        fs.write(r)
