GraphX is Apache Spark's API for graphs and graph-parallel computation.
GraphX is a new component in Spark for graphs and graph-parallel computation. At a high level, GraphX extends the Spark RDD by introducing a new Graph abstraction: a directed multigraph with properties attached to each vertex and edge. To support graph computation, GraphX exposes a set of fundamental operators (e.g., subgraph, joinVertices, and aggregateMessages) as well as an optimized variant of the Pregel API. In addition, GraphX includes a growing collection of graph algorithms and builders to simplify graph analytics tasks.
Apache Giraph is an iterative graph processing system built for high scalability. For example, it is currently used at Facebook to analyze the social graph formed by users and their connections. Giraph originated as the open-source counterpart to Pregel, the graph processing architecture developed at Google and described in a 2010 paper
Gephi is an interactive visualization and exploration platform for all kinds of networks and complex systems, dynamic and hierarchical graphs.
Linkurious.js is an active fork of Sigma.js. It's dual-licensed under both GPLv3 and a commercial license for proprietary projects.

Plugin sigma.neo4j.cypher provides a simple function, sigma.neo4j.cypher(), that will run a cypher query on a neo4j instance, parse the response, eventually instantiate sigma and fill the graph with the graph.read() method.
Plugin sigma.parsers.gexf provides a single function, sigma.parsers.gexf(), that will load a GEXF encoded file, parse it, and instantiate sigma.
