These observations might be of mere academic interest except that studies have shown that not all observers interpret pie charts in the same way, One study, for example, found that 51 percent of pie chart viewers focused on the arcs of their sectors, 23 percent evaluated them according to their central angles, and only 25 percent interpreted them according to their areas.
One such feature is"explosion," as illustrated in Panel A of Exhibit 2 (and which was incorporated into the designs of nearly one-third of all pie charts the authors observed, and nearly 40 percent of all rotated charts).

What is the relationship between pie chart and scale measures of identity?
To address this question, the correlations between scale measures of identity and the PII and PII-CG, and the correlations between pie chart measures of identity and the PII and PII-CG, were compared at the role and the domain level (but not across levels).
