In the last couple of month I’ve started to experiment with data. Won’t call it big data, because my datasets are rather small. Like visitors in our holiday apartments or feedback from EclipseCon Europe attendees. But like a real guy I didn’t want to do with MySQL, I wanted to play with the the new toys. So I installed MongoDB.
Anyway, it turned out to be more difficult than I thought. Cleaning up the data and getting them in (the same) shape turned out to be harder than I though. But help was just around the corner – coming from Udacity: A course on Data Wrangling, just what I needed. Turns out it was just the right course at the right time. And forgive me, if I don’t bore you with all the details that I had to clean up.
I’m certainly not a big data expert yet. But I start to understand how to approach my problems and what I can do with my information. And visualizing that information is even more fun. Now you can guess what that heatmap shows 🙂
