Try the attached.
Thank you so much! Looks great and exactly like I wanted. :-)
I tried karbon, but I'm beginning to believe karbon is
user-hostile. I am able to draw a diagonal line with
libreoffice draw, but I cannot figure out how to draw a
line with rounded ends and found no help online.
An examination shows that Karbon has no pen tool, which really should be added. It also has no obvious way to delete individual points from a shape (if it did have, you could have scribbled a pencil line then deleted the intermediate points to straighten it). These are pretty serious deficiencies for what's supposed to be a usable vector editing application.
Thank you for your observations. I won't pretend to have much knowledge about drawing apps and therefore won't pretend I have standing to complain. But basics are basics and new users should be able at least to draw a simple line.
I tinkered some more with libreoffice draw, but still can't draw a line with rounded ends. I drew a rectangle with round edges. Looked nice until I realized libreoffice draw had changed the borders from "dashed" to solid/full all around the image. Not sure what is up with that. Yet as a basic drawing app, I think I can learn and adapt to libreoffice draw. Too bad karbon can't do the basics.
