Same data, Different visual forms: data visualization for scientific discovery

 Small multiples of numbers, illustrating the value of creating many charts with the same data, but using color to highlight different aspects of that data

Moss Landing Marine Laboratories seminar series

In January 2018, I kicked off the spring seminar series at the Moss Landing Marine Laboratories Seminar Series, speaking about data visualization to a group of scientists, researchers, and students.

Abstract: Picking the visual form for a data visualization is a decision about what part of our data we care most about. Should we highlight outliers? Focus on the densest parts of the data? Ignore numbers under a certain threshold? Look at values or differences? The right form depends on what we believe is most important to see. Zan Armstrong will describe how to think about your goals and constraints in the context of visualization, look at your data in meaningful ways, use color intentionally, and create small multiples (many versions of the same charts, varying either categories of data or visual form in each).

 Highlighting technique with small multiples. Each chart represents a different binning of barometric pressures. Dark blue is raining lots, light blue raining a little, and grey for no rain.
