I've been mostly using the VS Code Excalidraw plugin. Any file with name ending on `.excalidraw.svg` or `.excalidraw.png` is an Excalidraw-editable image of the respective format. This means you can save it alongside your markdown docs and embed them directly, but also edit the exact same file on the IDE.
Big Excalidraw fan and I had no idea you could do that...this might be the version controllable solution I've been looking for. Also have given up trying to get mermaid and other solutions to work well.
