It would be possible to do that, but it doesn't act that way currently.

Yes. The gnuplot interactive terminals do full pan/zoom, although the
mouse interface is a little different from your example.
The options for embedding in a web page are not quite as feature-full.

See demos here based on using HTML5 2D canvas:
This output mode support zoom but not pan.
It also supports user-defined hot key operations,
but the demo does not exercise this.
