In words, the inequality says that the distance z−i between z and i should be strictly greater than 2 and less than or equal to 3. This means that the inequality defines an annular set having an inner radius of 2 and outer radius of 3, with centre at i.

The inner dashed circle is not included in the set; on the other hand, the outer solid circle does.
