  "Description": "Tools for generating hierarchical exploded-view maps from\ndense administrative boundary data. The package applies\nrigid-body translations to polygon geometries using a\ncentroid-driven vector field, preserving the internal geometry\nof each feature while separating units within and across\nregions. Parameters can be derived analytically from dataset\ngeometry using closed-form models for regional separation and\nlocal expansion. The package also includes grouped layouts,\noptional bounded collision refinement, and an interactive\nfocus-map widget for selected-area inspection in 'htmlwidgets'\nand 'Shiny'. It implements the methodology described in George\nArthur (2026) <https://github.com/PrigasG/explodemap> \"A\nHierarchical Vector-Based Framework for Multi-Scale\nExploded-View Cartography\".",
