I was able to figure this out with the help of an older piece by N.
Cox (2004): "Speaking Stata: Graphing distributions."

Run margins, then store estimates and confidence intervals as new
variables- I called them est lb and ub
gen pipe="|" if [var]!=. to produce the line to draw, since a pipe is
not a default option
gen where=0 to anchor the plot on the graph at 0

Plot and connect the dots, and overlay the pipes:
twoway connected est lb ub [var] || scatter where [var], ms(none)
mlabel(pipe) mlabpos(0) legend(off)

I then did some quick editing in Graph Editor.
