Given the title I'm surprised there isn't a comment yet about the TeX ecosystem for diagrams:

  - PGF/TikZ
  - PGFPlots (building on the above)
  - PSTricks
  - Asymptote

Or the PIC ecosystem, https://pikchr.org/ is a modern implementation that generates SVG.

Do any of them do actual graph layout, though, or require the user to decide exact coordinates of each node and edge?

Is it possible to use these tools without the whole Kitchen sink that is TeX?
