  Infographics are visual representations designed for efficient and effective
communication of data and knowledge. One crucial aspect of infographic design
is the interplay between text and visual elements, particularly in circular
visualizations where the textual descriptions can either be embedded within the
graphics or placed adjacent to the visual representation. While several studies
have examined text layout design in visualizations in general, the text-visual
interplay in infographics and its subsequent perceptual effects remain
underexplored. To address this, our study investigates how varying text
placement and descriptiveness impact pleasantness, comprehension and overall
memorability in the infographics viewing experience. We recruited 30
participants and presented them with a collection of 15 infographics across a
diverse set of topics, including media and public events, health and nutrition,
science and research, and sustainability. The text placement (embed,
side-to-side) and descriptiveness (simplistic, normal, descriptive) were
systematically manipulated, resulting in a total of six experimental
conditions. Our key findings indicate that text placement can significantly
influence the memorability of infographics, whereas descriptiveness can
significantly impact the pleasantness of the viewing experience. Embedding text
placement and simplistic text can potentially contribute to more effective
infographic designs. These results offer valuable insights for infographic
designers, contributing to the creation of more effective and memorable visual
representations.
