This document provides guidance on how to effectively use visual aids when presenting. It discusses introducing visuals, commenting on visuals, and describing changes and developments. When introducing visuals, it is important to get the audience's attention and explain the purpose. When commenting, highlight important parts and draw conclusions. A variety of words like increase, decrease, rise, and fall can be used to describe changes shown in graphs, charts, or diagrams. Precise figures are usually not necessary; instead, emphasize overall trends and approximate numbers.
