The world’s data is growing. In 2011, we created almost 2 trillion gigabytes. Recent studies suggest online data can be used to improve forecasts of stock markets, track a crisis in real time, and glean new insights into an economy. Yet, we have no way for people to instantly explore and understand this enormous treasure. Here at the University of Warwick and University College London, we are building Tree: a data engine that lets you instantly explore online data, make remarkable discoveries and tell meaningful stories.
