graphics-design and synonomized graphic-design had 20-odd questions and the tag was undefined.
Since graphic design isn't really on-topic, I looked at the associated questions. Most were just unrelated decoration, so I cleaned them up.
Only three remained, one of which was closed as a duplicated of a closed question. These were about graphics editing rather than graphic design. Since there were only a couple, I went ahead and retagged those with the existing but little-used graphics-editing tag.
The deprecated graphics tag has over 400 questions, and I suspect many of them can be retagged with graphics-editing. graphics-editing was also undefined, so I drafted a wiki and wiki excerpt.
Which brings me to this question. graphics-design has two followers and is now empty, so it will disappear in a day. Some number of people relate to the term "graphic-design" rather than "graphics editing" (given the difference in past tag choice). Suggestion: while they still exist, synonomize graphics-design and graphic-design with graphics-editing.
