Hierarchical Exploded-View Cartography // Tools for generating hierarchical exploded-view maps from dense administrative boundary data. The package applies rigid-body translations to polygon geometries using a centroid-driven vector field, preserving the internal geometry of each feature while separating units within and across regions. Parameters can be derived analytically from dataset geometry using closed-form models for regional separation and local expansion. The package also includes grouped layouts, optional bounded collision refinement, and an interactive focus-map widget for selected- area inspection in 'htmlwidgets' and 'Shiny'. It implements the methodology described in George Arthur (2026) https://github.com/PrigasG/explodemap "A Hierarchical Vector- Based Framework for Multi-Scale Exploded-View Cartography".
