magickGrob

Rasterize a grob object with magick

A 'ggplot2' extension providing an integrative framework for
composable visualization, enabling the creation of complex multi-plot
layouts such as insets, circular arrangements, and multi-panel compositions.
Built on the grammar of graphics, it offers tools to align, stack, and nest
plots, simplifying the construction of richly annotated figures for
high-dimensional data contexts—such as genomics, transcriptomics, and
microbiome studies—by making it easy to link related plots, overlay
clustering results, or highlight shared patterns.
