The plot server supports interactive plots that can be
viewed and navigated using HTTP requests.
A plot is specified with a URL, corresponding to an invocation
of one of the plot2* commands,
that specifies a plot, and uses
a service API that can be used by client-side javascript to
display and update a plot image in response to user navigation actions
such as mouse drag and wheel gestures.
The effect is of an interactive plot in a web browser that
can be navigated with the mouse in exactly the same way as
a STILTS or TOPCAT interactive plot.
To see this in action, run
% stilts serverpoint your browser at the URL displayed and follow the links to see some interactive plots.
The following subsections give some more details about how this works and how it can be used.
