For over a frakkin year I have had a booger of a time getting svg files that I made in a text editor to scale at all. Today for the first time I noticed that the word is "viewBox" not "viewbox." UGH! That makes all the difference in the world.
Here is today's play file so far. It has some vertical text that a web browser can read but zap doesn't know what to do with. Overall I am pretty dang happy with my drawing from a text editor.
