Names the file each visualization lands in, and the statements that build it.
A device opener (pdf("a.pdf")) takes every plot until the device is closed (dev.off()), so those plots
end up in its file instead of on screen; a plot outside any open device keeps the value it had. Every plot
that lands in a file also reports the statements it takes to produce that file in
DependencyInfo#parts: the addons drawn onto it, plus the device opener and closer around it.
Closing a device ends the plot, so an addon after it builds whatever device is open then, not this file.
Openers are the write entries that draw (CallProp.Graphics), closers the calls that end a device
(CallProp.Closes), and the order is the one the source states.
