It's fair to say we love data. I mean we've built a whole travel guide based on analyzing lots of data. We also love to share nice things we stumble upon while crunching data. During our Jamboree in Prague we had a hackathon and Ionut was looking at Instagram tags and what they tell us.
The above images shows us where most pictures are tagged with #castle in Central Europe. Neuschwanstein lights up, just like Prague, Bratislava. Paris is also shining brightly: zoom in to see that it's a combination of Versailles, Vincennes, Chantilly and Disneyland.
We've published an interactive heatmap you can play with in our Labs section.
