Why do you need data visualization?

Do you remember the filing cabinets of the ’90s? There would be entire rooms lined with the metal behemoths. They would contain all the memos, contact info, contracts – everything you could need, lost in the metal boxes. Today we’ve mostly moved away from all those metal boxes to just one – our computers. But that doesn’t mean we know how to access and use all that data. Those emails, memos, contact info contracts that are unused, they can be considered ‘dark data.’
