Sketch notes are used to create visual personal notes. These can be used in workshops, amongst other things, to directly visualize all ideas. Another form is the use of sketch notes to explain complex topics. For example, the German magazine Apotheken Umschau uses graphics from NadiNa rossa to explain placebo-controlled double-blind studies. This type of visualization is being used more and more frequently, especially in the doctor-patient and teacher-student context, to explain complex content to a wide audience.
