Tools to stream data to gephi

Project description


Python classes for streaming graph to gephi


`pip install gephistreamer`

Quick use

# Basic import
from gephistreamer import graph
from gephistreamer import streamer

# Create a Streamer
# adapt if needed : streamer.GephiWS(hostname="localhost", port=8080, workspace="workspace0")
# You can also use REST call with GephiREST (a little bit slower than Websocket)
stream = streamer.Streamer(streamer.GephiWS())

# Create a node with a custom_property
node_a = graph.Node("A",custom_property=1)

# Create a node and then add the custom_property
node_b = graph.Node("B")['custom_property']=2

# Add the node to the stream
# you can also do it one by one or via a list
# l = [node_a,node_b]
# stream.add_node(*l)

# Create edge
# You can also use the id of the node : graph.Edge("A","B",custom_property="hello")
edge_ab = graph.Edge(node_a,node_b,custom_property="hello")

How to

Use the `Streamer` class to describe the action to perform:
* add_node
* change_node
* delete_node
* add_edge
* change_edge
* delete_edge

Don't forget to have Gephi running with the plugin [Graph Streaming]( installed and active in "Master mode".
![Master mode](


The GephiWS class communicates with Gephi as Websocket call.


The GephiREST class communicates with Gephi as REST call.

Auto commit
By default, all action will trigger a "commit" and send information to Gephi. You still
can use the old way by requiering a
stream = streamer.Streamer(streamer.GephiREST(),auto_commit=False)
[.. actions ..]
stream.commit() # Will send all actions buffered to Gephi
