This second episode of Infra[un]structured uncovers everything you need to know about data visualisation. In the last two years alone, more data was created than in every year since the beginning of humanity combined. Charlotte draws upon the expertise of Vishal Kumar, a cultural data scientist, who uses open city data to understand the culture and science of cities. Also joining the discussion is Sakthy Selvakumaran, another member of the National Infrastructure Commission’s Young Professionals Panel and a civil engineer who is researching how satellite data can reduce the vulnerability of infrastructure within the urban environment.
