Caelum is the result of a three-week short project in the course "Data Visualization". We were tasked to develop an app that uses weather data in an alternative way, different from typical weather apps. My team partner and I decided to create an app that works opposite from the default weather app.

Instead of searching for a city and getting weather information we wanted to search for weather and find cities. This service could be useful for people that want to hike on the weekend and don't know where to go. Also, photographers could use this to capture exactly the scene they want to shoot.

The dominant part of the visualization is the use of color. Every step between 0°C and 29°C has its own color value to quickly give the user a sense of temperature.

The color schemes are divided in three ranges: 0°C - 9°C for the cold tones, 10°C - 19°C for the middle and 20°C - 29°C for the warm / hot colors. Together the colors combine into a seamless gradient.
