Creating a unit chart
Unit charts, also referred to as pictogram charts, display each unit of measure as a single mark or symbol. While other types of charts may be more effective and less cluttered, unit charts may create more engagement because of the images and visuals used.
In this recipe, we will create a unit chart that shows all the medals that were won by Canada in the Summer Olympics from 1896-2008.
