How to describe ANY visual material: 5 Basic Steps
There are 5 steps you have to take when you want to describe an image:
1. Describe what it looks like (diagram type) and what it shows (the main information)
2. Talk about its contents (axes X and Y; parts; pieces; columns and lines)
3. Highlight the trend: mention some outstanding data
4. Cover the details: mention important smaller pieces of information
5. Make a conclusion and provide your evaluation: what can we take away?
