Draw.io for Layered Drawings

Recently I discovered that the same feature exists for diagrams. The draw.io site lets you create layered diagrams, with similar tools like you'd find in a image editor. You can create layers, order them, place diagram objects in the layers, and hide/show layers as needed.

An example of where this came in handy was a project I was working on that had three variations on a diagram. The shared parts I placed in one layer, and I created three other layers for the parts that were unique to each of the three variations. I was able to toggle between the three variants by showing/hiding the layers. It was easy to export the three variants. And changes to the shared portion only needed to be made once.

Definitely try out draw.io for your next multi-layer diagram.
