Windows Metafile (WMF) vector image: GraphViz block diagram (.dot) source

WMF (Windows Metafile) is a relatively early vector image format introduced for Microsoft Windows in 1990.

Inside, it provides a serialized list of Windows GDI (Graphics Device Interface) function calls, which, if played back, result in an image being drawn on a given surface (display, off-screen buffer, printer, etc).
