The term "dotted line" refers to some kind of line or boundary made up of small, evenly spaced dots. There are several synonyms for "dotted line" that can be used interchangeably in different contexts. One alternative is "dashed line," which is similar in pattern to a dotted line but with small gaps or breaks between the dashes instead of dots. Another synonym is "dotted border," which is often used in design or graphic software to create a border with dotted lines. "Broken line" is another option that can describe a line that is interrupted or fragmented, often with dots separating the segments. Lastly, "stippled line" refers to a line that is made up of small, distinct dots that blend together to create a solid line effect.
