These are the design guidelines I teach. From halfway through this deck: www.mjskay.com/presentation...

These days (for academic vis) I'd add "ensure natural visual operations correspond to meaningful operations in data space". Need to make slides for that.

Some rough design guidelines*

1. Match effectiveness with importance
2. Avoid ambiguity
3. Locality is king / eyes beat memory
4. Establish viewing order
5. Layer, layer, layer
6. When in doubt, grid
7. Treat visual attributes like adjectives

* These guidelines are drawn largely from my experience + personal preferences + the literature.
Design is messy, these are not perfect, others will disagree with me, etc. Caveat emptor.

Why do we still need standardized journal abbreviations? It looks like something that was important to save space when journals were printed on paper, but are a complete waste of time nowadays.

Funny how, when two academics meet, the first thing they do is perform that “song and dance” ritual to uncover even the slightest overlap in their research interests.

Bittersweet moment for me... I've decided to leave Edge Hill University, my UK home for the past three years, to return to Brazil due to personal reasons. I'll deeply miss the amazing friends I've made here and all the memories we've shared. Thanks for making me feel so welcome!
