What should I write?
- A certain property is represented with a special color.
- A certain property is represented by a special color.
Or maybe even "indicated with/by"? But the main point of this question remains: with or by?
With and by signify 2 different meanings:
He was represented with his accomplices by the best lawyer available.
I think there is a difference in meaning.
by: something takes the place of and refers to something bigger, e.g., a country is represented by a flag or a team in an international competition.
with: an attribute with which something or someone is depicted, e.g., Saint Rita is represented with a bunch of flowers.
