We just conducted a visualization research and identified what we can term as the ‘Retention Effect’ of data visualization. Our target audience consisted of 64 persons of varying races and in the age range of 18 to 55. We presented data and diagrammatic descriptions of faces to Team A participants, and photographs to the members of team B. At the final audit a group of persons were brought into a room and respondents asked to identify the person under review. 98% of the team B respondents accurately identified the right person, while only 23% of the tam B respondents identified the right person. 40% of the team B respondents identified other persons who closely resembeled the textual descriptions the rest were unsure.
