[Gnuplot-info] Possible to highlight selected points when using hypertext?

[Kevin K. <kk...@gm...>]

I was reading about gnuplot's hypertext feature here:

http://gnuplot.sourceforge.net/demo_svg/hypertext.html

Is it possible to have the data points highlighted when they are moused
over, like in this plot using D3:

Also is it possible to create a pannable/zoomable graph in gnuplot that
acts like this one using D3:

In both cases I would want something created using gnuplot that could be
embedded in a webpage, as in the two examples above.

I realize the above two examples are using D3, but if it is possible to
replicate those effects in gnuplot?
