As data becomes easier and cheaper to generate, we are moving from a hypothesis-driven to data-driven paradigm in scientific research. As a result, we don’t only need to find ways to answer any questions we have, but also to identify interesting questions/hypotheses in that data in the first place. In other words: we need to be able to dig through these large and complex datasets in search for unexpected patterns that - once discovered - can be investigated further using regular statistics and machine learning. Interactive data visualization provides a methodology for just that: to allow the user (be they domain expert or lay user) to find those questions, and to give them deep insight in their data.

Content:

  • Background and context of data visualization and visual data analysis
  • Design as a process: framing the problem, ideation, sketching, design critique, …
  • Programming visualizations: static and dynamic
  • Project: visualization of expert dataset

Visualisation for communication - example

Here’s a nice example of what we mean when talking about visualisation for communication, using digitization data from the US Library of Congress: http://sappingattention.blogspot.com/2017/05/a-brief-visual-history-of-marc.html
