Best Diagramming Software

Diagramming software allows users to create detailed diagrams—such as flow charts and floor plans—out of data and images. Diagramming tools often include templates for building diagrams in addition to enabling users to create diagrams from scratch. Certain diagramming programs can integrate with other design tools, and may offer collaborative platforms so multiple users can view and edit diagram files at the same time.

To qualify for inclusion in the Diagramming category, a product must:

  • Offer specialized tools for designing one or more types of diagrams, such as organizational charts and floorplans
  • Provide industry-related shapes and elements for use in diagrams and allow users to create or import custom diagram components
  • Allow specified users to view and interact with diagrams online during and after presentations

    Diagrams are as powerful as they are versatile. They get people to see the big picture. They help teams vault over communication hurdles. They can be equally useful for looking at high-level plans or drilling down to the smallest detail. And, if you think there’s no inner diagramming Jedi waiting to awaken within you, give us a chance to prove you wrong. Visual Language is Universal Chances are, you’ve experienced the instant disorientation that sets in when you visit a country and don’t speak the language. You immediately regress to a time when you couldn’t read and symbols become your new best friends. Symbols can guide you to food, shelter and gas. They can help you avoid danger and tell you when to stop and when to go. Diagrams (comprised of multiple symbols) are even more powerful. A diagram can align a team, clarify a process, communicate a complicated idea and get departments with different areas of expertise to finally understand each other. Whether you’re a software engineer, a product manager, work in marketing or HR or just want to show your brilliant sense of humor, there’s a diagram for you.
