In Imagemagick command line (unix syntax), I would do the following. Get the height of your image and specify some width say 200. Then make a caption: image for your text. Than append them side-to-side.

height=`convert SeHrHLC.png -format "%h" info:`
convert SeHrHLC.png \
\( -background none -size 200x$height -fill black \
-font Arial -gravity west caption:"Hello Superman" \) \
+append \
result.png

Sorry, I do not know node or graphicsmagick. But imagemagick is very similar to graphicsmagick.
