I created the attached images in Illustrator.
On the first one (world map) I want to represent data going from one place to the other.
I had a path that I altered with the width tool, so one end is wide, and the other end ends in a small point. I duplicated this path and I used 'type on path' and in the 'type on path options', I aligned the text to the centre of the path. I had to adjust the text size character by character to fit into the orange 'beams' and I am wondering, is there a way to somehow automatically change text size, so it evenly follows how the beam is getting wider?
I also attached an image where spiraling letters are going from small to big, where I had the same problem.
Is there a way to evenly change size of text?
