From the creator:
I decided to dig deep into my browser history data for my data visualization project. Because I spend so much time online everyday, doing all sorts of things from working to socializing to just aimless wandering, I thought browser history alone could narrate a significant portion of my life and what was on my mind. A plus of using browser history was that the data was nice and easy to obtain. Therefore I could skip the trudge of collecting and cleaning the data and focus on the content itself.
