When used effectively, visuals help a writer or presenter convey information to their audience. For example, recently, British Columbia's (BC's) Public Health Officer, Dr. Bonnie Henry, and BC's Minister of Health, Adrian Dix, used graphics to help people understand the relationship between our level of social activity and the case rate of Covid-19 in the province, and in relation to other parts of Canada and the globe. Many people found the concrete data especially clarifying.

For other people, graphics can be challenging. Think about your own experience with graphics. What types of graphics do you find most helpful and what types do you find more challenging?
