In fact (my 2 cents) I would tend to use "chart" as the overall largest
object.  You could plot a course from (say) Normandy to Hastings on a
nautical chart but you could also plot a set of isobars on a map of your
local area and produce a "weather chart", plot a set of dance steps on
paper to produce a choreographic chart, etc.

My vision would be a chart is a single graphical output from the
underlying engine. On that would be one or more plots that depict a
certain set of data.

Certainly, "graph" has a particular mathematical meaning (nodes and
edges) that could have conflicts as abstract data types. I agree with
Tobi that it would be better to avoid it.

Nautically, a chart is a single instance of "a piece of paper" with
certain attributes like a title, a set of co-ordinates, some "pretty"
features, an identity etc that you use locally to plot a course or
something.  Also, although I'm linguistically challenged I believe that
"chart" and "plot" have fairly parallel translations - Carte,
Kart?,sjökort etc and tracer, plotten, plotta etc  whereas "graph" tends
to translate more generically as a "picture" - graphique, Grafik, graf
etc.
