Try to get an HP1350 or HP 1351 graphics translator, or graphics
generator. These are not all that
hard to find, and they generate excellent quality vectors, driven by a
GPIB interface.
Very cool, real vintage vector hardware!
And by the way, NO raster based display can ever do a credible job of
simulating a 'real' vector
display. The aircraft cockpit had ~real~ vectors, not a raster display,
and for a good reason.
Use real vectors, accept no substitutes.

A thought occurs to me: there is a piece of video
test gear called a
Vectorscope - used to determine the proper alignment of the TV color
signal phase vectors... anyway, a lot of companies, from Heathkit to
Tekronix, made these, and the older ones can be had at swpameets (or on
eBay) for pretty cheap.
Then, you'd have all the circuitry needed to drive the CRT (and quite
possibly a 4" CRT in the bargain)... the interfacing task is redused to
just DACs and opamps to feed the vectorscope guts....
I think if I had to produce a 'real' stroke display that's the route
I'd
investigate first.
