Sunrise, sunset, and sun altitude throughout the year: an interactive visualization
The yellow curve shows the sun's altitude above the horizon throughout the day, from sunrise to sunset. The yellow shadow behind it shows the full envelope of altitudes across the entire year, making the seasonal contrast immediately visible. It is especially dramatic at high latitudes.
You can drag the handle on the outer ring to pick any day. Further, you can pan and zoom the map to explore any location on earth.
Try it yourself: https://visquill.com/gallery?example=sun-map
Data source: astronomical solar position calculations via astronomy-engine.js
Tools: VisQuill (reactive geometry SDK in TypeScript), Leaflet for the map rendering, OpenFreeMap for the map tiles.
