Use diagrams in Confluence to illustrate a complex process or assembly to help users more easily understand complex information. Adding diagrams is simple, and there are two approaches you can use:
If you're moving documentation from another system into Confluence or if you just already have a diagramming app, you can add image files of those diagrams to Confluence just like any other image. Adding images of diagrams is useful when quickly adding existing content into your documentation or adding new diagrams without additional cost for a native diagramming tool. One major downside is that images of diagrams are not updatable in Confluence, so you have to update them in another app, export the diagram as an image, and then add it to the Confluence page. We don't recommend this approach because it detracts from the collaborative nature of documentation in Confluence.
The best approach to adding diagrams in Confluence is by using a Confluence app like draw.io Diagrams or Gliffy. With either of these apps, you can create and display diagrams dynamically within Confluence. Both also support collaboration and diagram versioning, so you can create diagrams as a team. Also, when a team member updates a diagram, the changes are immediately displayed on the page without the need for exporting and uploading image files.
