Why the Time-Tested Science of Data Visualization Is So Powerful

BERLIN and Narratives

BERLIN stands for Behavioural Event Reconstruction Linguistic Interface for Narratives. I introduced BERLIN a few blogs ago - in my "final blog."

Storytelling with Data: Our Brains Crave Structure + Love Oddballs
