This study examines the visual design processes and strategies used by graphic design experts and non-design college students when applying visual design principles to compose an infographic. The focus is on the visual design stage, often reported as challenging for adult and young students (e.g., Fragou & Papadopoulou, 2020; O'Mahony et al., 2019). The goal is to identify differences in the strategies utilized to produce higher and lower-quality infographics scored across 17 design criteria. This study employs a collective case study design, in which participants were asked to create an appealing and readable infographic and think aloud as they performed the task. Each participant was presented with identical ready-to-use text, icons, and shapes on a given topic and used the design tool to complete the task. The participants consisted of 5 graphic design experts recruited through snowball sampling and 5 non-design college students recruited through typical sampling. All sessions were recorded and transcribed for data analysis. Results revealed six visual design processes: (1) create structure and grid, (2) establish visual hierarchy, (3) define visual rules, (4) replicate visual rules, (5) test and adjust, and (6) validate and revise. Also, high-rated infographics were produced using a more systematic design process, starting with working on the structure and grid and establishing a visual hierarchy, and moving on to define and replicate visual rules, followed by testing and adjustments, and validation. Moreover, the study identified many design strategies from the comparative analysis between high and low-performers, such as: (1) using a breadth-first approach by laying out the elements over a grid and working on visual hierarchy before working on details, (2) placing related content near each other and less related content spaced apart to spatially organize and structure the content, (3) using up to two font styles and opting for legible fonts over decorative fonts, (4) testing various colors, fonts, and graphics while preserving the overall structure and hierarchy, and (5) stepping back to validate the overall design and making final adjustments based on the optical weight. These target processes and strategies were encapsulated into a five-stage Infographic Visual Design Model.
