Data Sources

We want honesty and transparency to be a key part of our data visualization experience. To help you compare ‘climate’ and ‘weather’ data in each visualization accurately, our baselines and our graph axis are kept the same. And, all of the data we use is freely accessible to you - you even can access the code too, if you want.

Most of the data we use comes from freely available data sources across Sweden.
