Mapper construction, leaf landmarks, and representative examples from grapevine and maracuyá morphotypes.

(A) Generalized overview of Mapper graph construction and lens function selection (see Materials and Methods for details). Each data point has a distance from every other and is assigned a real number value through a lens function, y in this case (left). Points are binned by overlapping cover intervals across the lens function, clustered into nodes, and edges placed between nodes spanning cover intervals with shared data points to create a graph (right). (B) Landmarks used for grapevine (left) and maracuyá (right). (C) Averaged leaf shapes representing grapevine species (left) and maracuyá morphotypes (right). Note: each species (grapevine) or morphotype (maracuyá) was assigned an arbitrary color which will be used consistently throughout the manuscript.
