Hi David,
I would like to change circles in your code to rect. I did the
following:
1. I change the backgroud from rect to polygon and it works.
2. I change the circle to rect by
a. change "circle" to "rect"
b. change "r:rad" to
"x:20",
"y:30" in the Atribute assignment
However, this will be work for me. What is wrong with my
modification?
By the way, what is the meaning of "id":stroke in your code? Why we
need to do that?
Thank you for your help.

BigArrayofCircles.push(Attr). Then whenever the user were to choose
a "save" option (from say a menu) the BigArrayofCircles (which has
already been serialized as an Object) could just be sent (via some
format like plaintext, JSON, or AJAX -- JSON seems likely since
that's close to what it is already) to a server (which would just
scribble it into a file somehow). The clientside program would then
just need a file open routine which would pretty much just be (after
identifying the particular BigArrayofCircles, among those saved to
the server, to be opened):
