dagre-py

Thin python wrapper around dagre-d3 for building quick dags with tooltips and a few other niceties. It’s not really generically usable right now, but you can try something like:

from dagre_py.core import plot

plot({
    "nodes": [
        {"label": "A"},
        {"label": "B", "description": "This is an output node"}
    ],
    "edges": [{"source": "A", "target": "B", "label": "edge1"},
              {"source": "A", "target": "B", "label": "edge2"}]
})

With the following effect:

It’s also possible to use an id field coupled with a label to disambiguate nodes that you want to have the same label. Where source and target fields in edges use node id instead of node label. For example:

from dagre_py.core import plot

plot({
    "nodes": [
        {"label": "A", "id": "A"},
        {"label": "A", "id": "B", "description": "This is an output node"}
    ],
    "edges": [{"source": "A", "target": "B"}]
})

With the following effect:
