The document discusses developing audience personas to help design visualizations that are empathetic. It recommends identifying key stakeholder groups and personas within each group by considering their motivations, priorities, knowledge level, and other human attributes rather than just job titles. An example is provided of mapping personas like "Rachel the Technocrat" and "Pascal the Politician" based on dimensions such as how they are motivated and how they act. The goal of personas is to focus on a manageable set of audience profiles to guide visualization design rather than attempting to account for thousands of individuals.
