Confusion and clutter are failures of design, not attributes of information. And so the point is to find design strategies that reveal detail and complexity - rather than to fault the data for an excess of complication. Or, worse, to fault viewers for a lack of understanding.

A metaphor for good information design is a map. Hold any diagram against a map and see how it compares.

Clutter is not an attribute of information, clutter is a failure of design...fix the design rather than stripping all the detail out of the map.

The essential test of design is how well it assists the understanding of the content, not how stylish it is.
