NAS Workshop: Visualizing Uncertainty

2D: Darkness = uncertainty (high stddev)
Mean
= hue
Skew
= 1/saturation
Stddev= 1/value
Currently, uncertainty is usually represented by scalar quantities.
At times, a pair of numbers may also be used e.g. min/max.
Additional second moment statistics may also be used.
