GraphSpace-class

GraphSpace: An S4 class for igraph objects

An interface for rendering 'igraph' objects as 'ggplot2' graphics
within a normalized coordinate space. 'RGraphSpace' implements new
geometries that treat a graph as a single coherent object, synchronizing
node and edge layers under standard aesthetic mappings. Node features are
resolved on demand, supporting high-dimensional data without expanding
node tables. Spatial alignment is available at the pixel level,
with node coordinates anchored to pixel centers through a half-pixel
offset, enabling precise node positioning over external reference frames
such as images and maps.
