DeepGraph

DeepGraph is a scalable, general-purpose data analysis package. It implements a network representation <https://en.wikipedia.org/wiki/Network_theory>_ based on pandas <http://pandas.pydata.org/>_ DataFrames <http://pandas.pydata.org/pandas-docs/stable/generated/pandas.DataFrame.html>_ and provides methods to construct, partition and plot networks, to interface with popular network packages and more.

It is based on a new network representation introduced here <http://arxiv.org/abs/1604.00971>. DeepGraph is also capable of representing multilayer networks <http://deepgraph.readthedocs.io/en/latest/tutorials/terrorists.html>.

Main Features

This network package is targeted specifically towards Pandas <http://pandas.pydata.org/>_ users. Utilizing one of Pandas' primary data structures, the DataFrame <http://pandas.pydata.org/pandas-docs/stable/generated/pandas.DataFrame.html>_, we represent the (super)nodes of a graph by one set of tables, and their pairwise relations (i.e. the (super)edges of a graph) by another set of tables. DeepGraph's main features are

• Create edges <https://deepgraph.readthedocs.io/en/latest/api_reference.html#creating-edges>_: Methods that enable an iterative, yet vectorized computation of pairwise relations (edges) between nodes using arbitrary, user-defined functions on the nodes' properties. The methods provide arguments to parallelize the computation and control memory consumption, making them suitable for very large data-sets and adjustable to whatever hardware you have at hand (from netbooks to cluster architectures).

• Partition nodes, edges or a graph <https://deepgraph.readthedocs.io/en/latest/api_reference.html#graph-partitioning>_: Methods to partition nodes, edges or a graph by the graph’s properties and labels, enabling the aggregation, computation and allocation of information on and between arbitrary groups of nodes. These methods also let you express elaborate queries on the information contained in a deep graph.

• Interfaces to other packages <https://deepgraph.readthedocs.io/en/latest/api_reference.html#graph-interfaces>_: Methods to convert to common network representations and graph objects of popular Python network packages (e.g., SciPy sparse matrices, NetworkX graphs, graph-tool graphs).

• Plotting <https://deepgraph.readthedocs.io/en/latest/api_reference.html#plotting-methods>_: A number of useful plotting methods for networks, including drawings on geographical map projections.

Quick Start

DeepGraph can be installed via pip from PyPI <https://pypi.python.org/pypi/deepgraph>_

::

$ pip install deepgraph

or if you're using Conda <http://conda.pydata.org/docs/>_, install with

::

$ conda install -c conda-forge deepgraph

Then, import and get started with::

import deepgraph as dg help(dg)

Documentation

The official documentation is hosted here: http://deepgraph.readthedocs.io

The documentation provides a good starting point for learning how to use the library. Expect the docs to continue to expand as time goes on.

Development

So far the package has only been developed by me, a fact that I would like to change very much. So if you feel like contributing in any way, shape or form, please feel free to contact me, report bugs, create pull requestes, milestones, etc. You can contact me via email: [email protected]
