Python equivalent of D3.js

Question

Can anyone recommend a Python library that can do interactive graph visualization?

I specifically want something like d3.js but for python

Answer 1

See:

Is there a good interactive 3D graph library out there?

The accepted answer suggests the following program, which apparently has python bindings: http://ubietylab.net/ubigraph/

Edit

I'm not sure about the interactivity of NetworkX, but you can definitely make 3D graphs. There is at least one example in the gallery:

http://networkx.lanl.gov/examples/drawing/edge_colormap.html

And another example in the 'examples'. This one, however, requires that you have Mayavi.

Answer 2

There is an interesting port of NetworkX to Javascript that might do what you want. See http://felix-kling.de/JSNetworkX/

Answer 3

You could use d3py a python module that generate xml pages embedding d3.js script. For example :

import d3py
import networkx as nx

import logging
logging.basicConfig(level=logging.DEBUG)

G = nx.Graph()
G.add_edge(1,2)
G.add_edge(1,3)
G.add_edge(3,2)
G.add_edge(3,4)
G.add_edge(4,2)

# use 'with' if you are writing a script and want to serve this up forever
with d3py.NetworkXFigure(G, width=500, height=500) as p:
    p += d3py.ForceLayout()
    p.show()

Try https://altair-viz.github.io/ - the successor of d3py and vincent. See also

Answer 5

You can also choose to serialize your data and then visualize it in D3.js, as done here: Use Python & Pandas to Create a D3 Force Directed Network Diagram (It comes with a jupyter notebook as well!)

Here is the gist. You serialize your graph data in this format:

import json
json_data = {
  "nodes":[
    {"name":"Myriel","group":1},
    {"name":"Napoleon","group":1},
    {"name":"Mlle.Baptistine","group":1},
    {"name":"Mme.Magloire","group":1},
    {"name":"CountessdeLo","group":1},
  ],
  "links":[
    {"source":1,"target":0,"value":1},
    {"source":2,"target":0,"value":8},
    {"source":3,"target":0,"value":10},
    {"source":3,"target":2,"value":6},
    {"source":4,"target":0,"value":1},
    {"source":5,"target":0,"value":1},
  ]
}
filename_out = 'graph_data.json'
json_out = open(filename_out,'w')
json_out.write(json_data)
json_out.close()

Then you load the data in with d3.js:

d3.json("pcap_export.json", drawGraph);

For the routine drawGraph I refer you to the link, however.

Answer 6

I've got a good example of automatically generating D3.js network diagrams using Python here: http://brandonrose.org/ner2sna

The cool thing is that you end up with auto-generated HTML and JS and can embed the interactive D3 chart in a notebook with an IFrame
