City Explorer

Project Overview

This project demonstrates how raw population data, originally provided in CSV format, can be transformed into an engaging and unconventional 3D data visualization experience. 

Each building represents one of the 24 most populous cities in the world in 2024. The height of each building is scaled according to the city’s population, allowing users to immediately perceive relative population sizes through spatial visual cues.

As the player character approaches a building, an interactive data panel appears, displaying information loaded dynamically from a JSON file, including city and country name, population figures, and a line chart visualizing population trends.

• Character movement:
• w/up arrow - forward
• a/left arrow - to the left
• d/right arrow - to the right
• s/down arrow - backward
• Space - jump
• Mouse - rotate and move the camera
