Communication design involves using visual elements like images, text, color, and layout to convey messages and ideas to audiences. It can be considered both an art and a science. Graphic designers use tools like point, line, shape, texture, space, size, typography, color, and images to achieve communication objectives. They must determine what information needs to be conveyed, the order and hierarchy of ideas, how to guide the eye across the page, the intended tone, and target audience. Creative techniques used in advertising can also be applied to engage audiences and change perspectives through attention-grabbing images and emotions. Questions from the audience are then welcomed.
