Thanks for your response. I do see what you are getting at, and I don't disagree with you. If the chart is perceived as a bar chart, which people are apt to do and perhaps even what the author intended, the graphics are not proportioned correctly. The author's choice to use such large icons, in representing such small counts, definitely distorts the perspective.

I agree that the chart does not meet the self-sufficiency principle, but I don't agree with your interpretation that the scale is distorted. Showing the full center heart is not a problem. All of the hearts are half-overlapped, the side of the overlap just changes in the center. In your final illustration, the index for each heart should fall at the center of the heart. Then the graph properly represents six. For your area illustration to work, each bar would have to be overlapped with the subsequent bar. I believe this is only a consequence of using a finite area icon to represent an infinitesimal point. The icons are particularly large, in this case, but it's not possible to avoid this problem in any graph that uses points instead of lines. The thickness of the point will extend beyond the value represented. Let me know if I've missed your point.
