The tower of GDP

This course was about understanding the basics of visual programming, specifically through Processing. Although this wasn’t a data visualization course, I chose to work with data as a starting point for my explorations to create something which would reflect the characteristics of a specific subject. After exploring different directions, I ended up creating a tool that generated a 3D model, which I later imported and rendered in a separate 3D software.

The data is the GDP per capita of all countries of the world. Each slice represent a country. The height of each slice represents the population. The data spans over time. This is mapped circular in each slice, like a clock. Each outer point of the slice represents the relative value of GDP (PPP) for that specific year and country.
