Yes.

So ignore the html and just look at the png output graphs with the
png viewer of your choice.  You could multipane, 3D wheel, carosel, etc.

Or a simple Python script with some GUI buttons.

Pretty much any pnng viewer can do that.  Granted the png resolution may be
too low, but that is an easy fix.

ntpviz only takes 20 seconds to run on a Pi3 for me, ant then I have
all the graphs.  Or just ask ntpviz for the one graph you want, prolly
about a second,
