3.2 Aims: Exploration vs. Explanation/Presentation
- Exploratory graphs: “forces us to notice what we never expected to see” (Tukey 1977, vi)
- Audience: Ourselves (during research process)
- Objective(s): Explore and interact with the data (size, complexity, characteristics, distribution)
- Approach: Produce many graphs (quick and dirty)
- Explanatory graphs: “forces readers to see the information the designer wanted to convey” (Kosslyn 1994, 271)
- Audience: Others (of different characteristics) at the end of our research
- Objective(s): Show to, communicate to and convince others (tell story)
- Approach: Produce a final graph that is carefully crafte (and beautiful)
- Rapprochment between strictly exploratory and confirmatory appraoches (Healy and Moody 2014, 113)
- Interactivity is great for exploration!
