Unit Visualizations for Visual Storytelling

This case study is conducted by Le Devoir, a French-Canadian independent daily newspaper based in Montreal. This newspaper gathers about 50 journalists and attracts around 1 million readers every week. In the last six months, we published several visual stories using uniform unit visualizations. This type of visualization represents each data item as a specific visual element of constant size (e.g. square, circle, etc.). This case study details why unit visualizations can be particularly efficient representations for data-based visual stories. We also highlight the challenges and perspectives of such practice.
