The truism that a picture is worth a thousand words is true, but profoundly unhelpful. It doesn’t provide any guidance about which types of picture should be matched with which types of words.
This problem is the focus for one of the virtual toolboxes in our Verifier framework for spotting errors in expert reasoning. This toolbox deals with systematic ways of mapping data, information and knowledge onto the appropriate type of visualisation, or feature of a visualisation, such as line length or pattern or shape.
