If it is a symbol, yes.  If it is a model, no.

Absolutely.  _Everyone_ does that.

That's right.

Nobody looks at the word "tree" and knows what it means without prior
instruction.  People look at the word and visualize a tree because they have
learned to associate the symbol (the word "tree") with the object it symbolizes
(a real tree).

In contrast, a person can look at a painting of a tree and see a tree without
knowing anything about trees in advance.  That is because a painting actually
models a tree, it doesn't just symbolically represent one.

Yes.

A digital representation is symbolic; it is not a model.  You can only
understand a digital representation by referencing a common concordance between
the symbols used and their canonical meanings.

Right.

No, they are not.  You actually measure the length of the lines to get the
values they represent.  You don't have to know anything about the numbers to
begin with.  And any inaccuracy in the length of the lines or your measurement
will corrupt the information they are intended to communicate.

> What is it exactly that the drawn circle is representing?

A circle.  But since you cannot draw a perfect circle, the representation is
always slightly corrupt.

> The mathematics are describing the representation?

The mathematics allow you to create an identical circle of your own.  Zero loss.
A digital representation.
