What is a diagram?

Diagrams are simplified illustrations that explain ideas, structures, and processes. They also show how parts work together and how things relate. Diagrams are diverse; some compare and contrast, some show relationships, while others map out cause and consequence. But no matter the type of diagram, one thing remains the same: diagramming makes complex things easy to understand.

Frequently Asked Questions

It depends on the type of diagram. Different diagrams have different components. For example, a family tree diagram looks like a tree with nodes and branches. Meanwhile, a block diagram has blocks connected by arrows, and a cycle diagram consists of elements arranged in a circle, also connected by arrows. Diagrams are diverse, so the look will depend on your data.

Use our online whiteboard tool to make diagrams online for free. Our free templates get you started quickly, and there’s a free media library to help you customize your diagram. Download our app, too, so you can go diagramming anytime, anywhere.

A graph usually represents numerical data and quantifiable variables. Graphs make it easy to understand and interpret statistical information. In contrast, a diagram usually illustrates things that are more abstract, like concepts, structures, ideas, or parts of a whole. It shows how something works or how one thing relates to another.

A good diagram is clear, readable, and well-designed. Make sure your team uses the right diagram for the concept or data. The arrangement must be tidy—use spaces and borders to distinguish each section of the diagram. Use colors to group things together. For typefaces, stick with a single font, then use different font weights (light, bold, etc.) to highlight information. Our diagram maker offers lots of good examples of clear, well-designed diagrams.

Different types of diagrams have a different purpose. When you make Venn diagrams, for example, you aim to compare and contrast. When you make a fishbone diagram, you aim to find out the root cause. There are as many purposes as there are diagram types, so you have to choose the right one for your data.
