Core Design Principles for Displaying Quantitative Information from Stephen Few (data display god!). Downloadable pdf.
These form the basis of a presentation given by Juice Analytics on the six principles of visual context:
* Principle of Proximity – Things that are visually close to each other are related
* Principle of Similarity – Things that look like each other (size, color, shape) are related
* Principle of Enclosure – Things that are enclosed by a shape are related
* Principle of Closure – We see incomplete shapes as complete
* Principle of Continuity – Things that are aligned are related
* Principle of Connection – Things that are visually connected are related

Idea: Guidelines for stakeholder-focused evaluation graphics
Research from colleagues at Berkeley.
- 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.

Need to find the original – are these research based?
The graphics team at the New York Times talk about their work in constructing stories, editing content, and making information come alive in this video podcast from the team at gestalten. Note, they do it without a style guide for graphic design.
The mother-load. looks at metrics, information visualization, research, standards. Focus here is on how to judge information visualizations.
