A scientific diagram is a visual description that depicts the specific setup of an experiment. Most of the time science diagrams are in two dimensions. They must be very clear, exact, and simple to comprehend. Usually, a science diagram includes drawings or maps or illustrations. It starts with a drawing title. Each drawing must have the necessary labels and annotations. There is a scale bar. When a scale bar is included, the drawing or map does not need to be printed to a certain size, in addition to making map and drawing reading easier. There is no shading and sketchy line in a science diagram. It only contains stippling and single lines.
