RGraphSpace: Rendering Graphs as Coherent Spatial Objects in 'ggplot2'

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. Core functionality builds on 'igraph', 'ggplot2', and 'tidygraph'; optional geometry and large raster-background images use 'sf' and 'terra' when installed.
