prepare_initial_nodes

Prepare initial node table for igraph conversion

internal

Built on graph theory and the high-performance 'data.table' framework,
this package provides a comprehensive suite of tools for tidying, pruning,
and visualizing animal pedigrees. By modeling pedigrees as directed acyclic
graphs using 'igraph', it ensures robust loop detection, efficient
generation assignment, and sophisticated hierarchical layouts. Key features
include standardizing pedigree formats, flexible ancestry tracing, and
generating legible vector-based PDF graphs. A unique compaction algorithm
enables the visualization of massive pedigrees (e.g., in aquaculture
selective breeding population) by grouping full-sib families, maintaining structural
clarity without overcrowding.
