This is a circle packing diagram that, as a static image, doesn’t look like much.
Each of the white circles represents an individual Piers Plowman manuscript. Circles are ROUGHLY sized proportional to the number of lines of Piers poetry contained in each manuscript. Lines are estimated based on variations accounted for in the Kane editions and can be viewed in the JSON on the live bl.ock.
Grades of blue circles represent sub-categories of manuscripts based on the textual contents of each. Categorizations take note both of distinct combinations of A, B, and C text and of differentiations between how much text or how much of each are in a given sample of Piers Plowman.
