Perceptual Guidelines for Creating Rectangular Treemaps

Research from colleagues at Berkeley.

http://vis.berkeley.edu/papers/treepercept/

Design Guidelines:

  • Use Treemap Layouts that Avoid Extreme Aspect Ratios
  • Use Bar Charts at Low Density, Treemaps at High Density
  • Use Treemaps When Comparing Non-Leaf Nodes
  • Use Luminance To Encode Secondary Values In Treemaps

Also includes review of research to date.

David McCandless at TED – The Beauty of Data Visualization

McCandless is always interesting and finds intriguing examples – but often does not demonstrate outstanding design principles. Raises concerns for me, but brings data design to pop culture.

Need to find the original – are these research based?

Hans Rosing at TED – Global Population Growth

Rosling always makes me think. I love this presentation in particular because he uses manipulatives – IKEA boxes, to illustrate his data visually. And, the boxes add a dimension that I don’t think could be achieved technologically.
