The field of data visualization and information mapping has historical roots that date back far earlier than most people would imagine. Micronesian explorers created navigation charts with sticks and shells for thousands of years before the introduction of electronic navigation technology. Hundreds of years ago, humans had the means to mechanically collect data on everything from the pulse of ocean tides to the pulse of a living heartbeat. Data storyteller RJ Andrews is on a mission to showcase the work of the visionaries who carved the path for those of us working in the field of cartography and information design, and through his latest book series, “Information Graphic Visionaries” he has accomplished this mission with astounding success.
