I just gave a shot at the dataset and came up with my first Processing visualisation.

It aims to represents how the temperature has evolved over time in different regions of the Earth:
- North represents the data recorded by stations between the Arctic Circle and the Tropic of Cancer.
- Tropic represents the data recorded by stations between the Tropic of Cancer and the Tropic of Capricorn.
- South represents the data recorded by stations between the Tropic of Capricorn and the Antarctic Circle.
I am preparing a blog post with some further analysis of the data. All feedback is very much appreciated :)
