Mollie Pettit: Visualizing Data


Making decisions with data requires some form of communication with data. But how do we communicate with numbers and characters and binary bits? The best way today is through data visualization.

Visualizing data has come a long way since the early days of hand-drawn charts and graphs. Starting with the desktop publishing revolution of the 1980s through to the current world of data viz tools in the cloud, anyone can create a graphical representation of data. While in many ways this democratization of data visualization is a good thing, it also means we're awash with charts and graphs, many of which unintentionally don't tell the story intended. Some intentionally mislead.

Visualizing data well is more complex than you might think and that's why we reached out to a true expert in the field, Mollie Pettit, to talk about how she approaches visualization. In particular, we were interested in some of the more complex issues like how to visualize confidence in data.
