What is a diagram?

A diagram is a symbolic representation of information that helps you visualize concepts. It shows the arrangement of ideas or elements and how they relate to one another. Today, you’ll find diagrams in numerous fields, including education, writing, engineering, and marketing.

How to create a diagram with Lucidchart

  1. Decide what type of diagram you need

    There are a lot of different types of diagrams, so begin by determining which will best help you organize your ideas. Then, open a blank canvas or use a template from our gallery.

  2. Add shapes to your diagram

    Drag and drop objects onto your canvas. Click on individual shapes to move, rotate, and resize them as needed.

  3. Connect the shapes

    Click the red node on any shape and drag a line to connect it to another shape. Double-click lines to add text or use the properties bar to change formatting.

  4. Format your diagram

    Change the look and feel of your diagram by fine-tuning the layout, updating the fill and border colors of your shapes, and adjusting lines as needed.

  5. Collaborate, analyze, improve, and share

    Share your diagram with others to brainstorm solutions to problems, create action items, and more.

The best way to create a huge master diagram would be to link a few different diagrams together using Hotspots. Hotspots are essentially shapes in Lucidchart that link to other webpages. You could create your larger master diagram, then create Hotspots that link to separate smaller Lucidchart diagrams for marketing or other functions. So, when you follow the flow in the larger diagram and reach the end of one branch, you will reach a Hotspot link that will take you into a separate diagram.
