Building analyzing and visualizing large graphs


Ashwin Rajeev


A tutorial on how to model, use and visualize large graphs on existing storage systems.


A lot of real world problems can be solved better using graphs. In my talk I cover the basics of solving daily problems using graphs, modeling and building larger graphs on existing back-end systems (in- memory,relational,NoSQL). The talk will also cover some simple algorithms and tools to analyze and visualize such graphs.

The lecture will be geared towards programmers

Brief overview:

  • Spotting graphs in your data.
  • Graph models -mostly theory, I’ll keep it short.
  • How to model, and program large graphs(millions of nodes and edges).
  • Persisting such graphs on existing storage architectures (when switching to a graphDB is not an option or an overkill).
  • Visualizing huge graphs -what tools exist and how to build your own, some algorithms for effective visualization.
