Encontrei em um dos blogs da Harvard Business um post interessante sobre visualização de dados, com um exemplo de visualização que vem lá da segunda guerra mundial.
About ten years ago, I vividly remember visiting the Cabinet War Rooms in the basement of Whitehall, where Churchill had his war room during WW II. The desks were full of phones, and the walls covered with maps and information about troop levels and movements. These used color coded pieces of string to help Churchill’s team easily understand what was happening.
On the one hand, I was struck by how primitive their information environment was only sixty years ago. But on the other, I found it reassuring to see how similar their approach was to war fighting today. The mode, quality and speed of data capture has changed greatly from the 1940s, but the paradigm for visualization of the terrain, forces, and strategy are almost identical to those of WWII.
No post o autor ainda aponta 3 bons motivos para apostar nos dados:
Great visualizations are efficient — they let people look at vast quantities of data quickly.
Visualizations can help an analyst or a group achieve more insight into the nature of a problem and discover new understanding.
A great visualization can help create a shared view of a situation and align folks on needed actions.
