Identifies the type of figure being displayed, for example, a cartoon, chart, diagram, drawing, exhibit, illustration, map, plate, schema, workflow, etc.
This attribute was created to preserve existing semantic content when converting from a publisher’s Tag Set. Many Tag Sets make a distinction between different types of graphical objects (some by means of attributes, others with distinct elements). In the NCBI Book Tag Set and the NCBI Collection Tag Set, all these figure types will be tagged using the <fig> element. The distinctions between different types of figures can be preserved using the fig-type attribute, e.g., by recording the content type of the figure, such as “diagram”.
