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
