We, humans, are visual creatures. We evolved reasonable abstraction capabilities but we shine when we can visualize the problem at hand.
This is why I’m a big fan of Data Visualization as a discipline. Data has the answers. Visualization helps us better understand and interpret them.
(For a great introduction to the subject, consider taking the Data Visualization course by my colleague Alex Aklson, Ph.D.)
Perhaps, above all, I like the exploratory nature of visualizing data. We must be mindful of clustering illusions and type I errors, but it’s fun to explore unbridled, feeding our intuition and the part of our brain that seeks patterns.
