UNIT CHART TABLEAU TUTORIAL

According to Robert L. Harris in Information Graphics: A Comprehensive Illustrated Reference, a unit chart is
defined as follows:
A chart used to communicate quantities of things by making the number of symbols on the chart
proportional to the quantity of things being represented. For example, if one symbol represents ten
cars and five symbols are shown, the viewer mentally multiples ten times five and concludes that the
group of symbols represented 50 actual cars. Simple geometric shapes or irregular shapes such as
pictures and icons are generally used. Each provides basically the same degree of accuracy. When the
symbols are geometric shapes, the chart is occasionally called a black chart. When pictures, sketches,
or icons are used, the chart is often referred to as a pictorial unit chart. Unit charts are used almost
exclusively in presentations and publications such as newspapers, magazines, and advertisements.
