Based on our first meetup, we have a very wide set of interests and backgrounds that are interested in Graph's, Networks, and visualization. For this reason we are going to split up this next months talk into two parts:
What is a graph? (6:05-6:10)
Graph Formats and Visualization (6:10-6:40)
Graphs can be small, 20 nodes and 30 edges between them and can come from a .csv file. And graphs can scale to Billions of Nodes and Edges within a GraphDB like Neo4j- or even to trillions of edges like Facebook's Social Graph infrastructure.
Huston Hedinger, Founder and CEO of GraphAlchemist, will give a talk on different graph formats and how visualizations can be used to to tell a story with graph analytics. This talk will be very lightly technical, and should be useful with little or no background knowledge of Graph technologies.
Introduction to Cypher Query Language (6:40-7:25)
So there's this thing called the Graph... Graph DB's like Neo4j are optimized to store 'graphy' data, but how do I get the data out? Graph's can be queried just like any object oriented data base, additionally, they can be traversed to easily ask complex questions of the data, unthinkable (or at least not easy) in any other model.
Toby Craig, Cofounder and Lead Engineer at GraphAlchemist, will give a talk on the basics of Cypher, the primary method for querying Neo4j. Graph DBs are the most flexible and expressive data model, and Cypher is a language that parallels the flexibility of the graph in addition to having a very humane syntax. This talk will be technical, but the CQL learning curve is very straightforward if you are familiar with SQL.
