graphlay
Deterministic graph layout for Python: a layered (Sugiyama-style) engine with orthogonal or diagonal edge routing, a tidy-tree layout, quality metrics and an SVG renderer. The engine is graphlay, written in Rust. The wheels are prebuilt, so there is nothing to compile.
pip install graphlay
import graphlay
g = graphlay.Graph()
g.node("start", width=60, height=30, shape="ellipse")
g.node("work", label="Do the work")
g.node("end", width=60, height=30, shape="ellipse")
g.edge("start", "work")
g.edge("work", "end")
drawing = graphlay.layout(g, preset="process_map", options={"routing": {"style": "diagonal"}})
drawing.positions() # {"start": (x, y), ...}
drawing.edges[0]["points"] # the polyline, border to border
drawing # in a notebook: the drawing itself
drawing.sketch().save("drawing.svg")
A networkx graph works directly, and positions() feeds networkx.draw:
import networkx as nx
g = nx.DiGraph([("a", "b"), ("b", "c"), ("a", "c")])
pos = graphlay.layout(g).positions(flip_y=True)
nx.draw(g, pos)
drawing.sketch_scene() returns the same drawing as a scene dict. Change colours or labels in
it and draw it with graphlay.render_scene(scene).
The guide explains the options and the gallery shows what they do.
