Yet when it comes to drawing a schematic, many people start from scratch or never even start. Instead, start with an image search, let Inkscape do the hard work, and refine the best parts of other schematics.

I will use a figure of mine as a case study:

This schematic encapsulates the oceanographic processes that I examine in my PhD. I use it in many presentations, my thesis, and my personal website.
