Design topic
Information design is the craft of making complex information understandable at a glance: data visualization, diagrams, and wayfinding. It draws on visual perception and typography but points them at a specific job, showing structure and relationships clearly rather than decoratively.
Alberto Cairo
Alberto Cairo's introduction to information graphics and visualization as tools for understanding, not decoration.
Cairo bridges journalism and data visualization, teaching you to design graphics that help people reason rather than just look impressive. It is the best starting point if you make charts and want a principled way to choose forms. Read it before Tufte for a gentler, more practical on-ramp.
