Show HN: Turn raw Segment analytic logs from S3 bucket into JavaScript objects

I was curious to see how users interacted with my site so I implemented Segment analytics. I wasn't able to find a free data visualizer for my analytics, so I'm creating my own. The goal is to simply enter your AWS credentials, and let the software do the rest. This is part one of the project: turning the raw logs into useful JS objects.

Part two will be creating a front-end dashboard to visualize the data. So far I'm looking at adding a log of actions by unique users, total # of visits to each page, total # of unique tracked actions, and a graph that shows traffic over time. Is there anything else you think might be interesting to visualize?
