Camunda is a simple app for creating technical diagrams. You can easily drag and drop any point and it will automatically create lines and arrows for you. You can also choose from different types of points which can be helpful, for example, for highlighting when a user receives an email from Intercom. Camunda allows exporting to SVG that makes it easy to colour trackable points in Sketch.

It's our SVG Sketch-a-thon. We've got Peter Nowell on who's the Sketchmaster to talk about SVG workflows, animation workflow, plugins for Sketch, and how working in software like Sketch is great but you should still know the code.
