# Tropical climate zone: an interactive geography lesson

I built this lesson to help a student prepare a geography presentation on the tropical climate zone (advanced secondary-school level). There are 13 chapters that you move through with the arrow keys, Space or the buttons, and along the way you get:

- a 3D globe with the equator and the tropics;
- climate charts for real weather stations;
- small simulations, for example of the monsoon;
- numbers with footnotes that point to a checked list of sources.

It's a static page that uses three.js for the globe and D3 for the charts, and the text is in Polish.
