Summary of Specific Feedback and Design Recommendations for Each of the Three Health Visualizations

	POSITIVE FEEDBACK	NEGATIVE FEEDBACK	RECOMMENDATIONS
Bar plot (Fig. 1)	• Familiar self-contained visualization • Provides for quick longitudinal comparisons • Allows for component comparisons	• Low, good, excellent ratings have no context. • Color gradient for group comparisons creates confusion. • Shadings for longitudinal display are too subtle.	• Remove color gradient from low to excellent • Separate holistic wellness graphs into components • Use solid color as opposed to shades
Radial plot (Fig. 2)	• Explicit colors as opposed to gradual shadings • Numbered wellness scores allow for direct comparisons	• Dots are difficult to count. • Colors are difficult to contrast. • Shapes are perceived as distracting.	• Individual wellness components • Connect dots for a solid ring
Light ball metaphor (Fig. 3)	• Brightness difference amplifies large changes. • Simplification of information • Accommodates color blindness	• Can only view one wellness component at a time • Dark background creates an ominous tone.	• Use an alternative colored background • Increase sharpness for comparisons
