Final Project - The Data Processing Pipeline

Well you got the job. You're chief analyst now and you're company wants to expand its analytics into new frontiers. It's time for you to build your own project from scratch. Here's what you need to do:

1. Find a data set.

2. Model the data.

3. Load it into a graph database.

4. Write a series of queries against the data.

5. Export a subgraph projection to NetworkX and perform analysis.

6. Create a series of visualizations of the subgraph with Gephi.

7. Prepare a detailed write up of your research.

8. Prepare a presentation of your project.
