## Overview
`plotgardener` is a genomic data visualization package for R. Using `grid`
graphics, `plotgardener` empowers users to programmatically and flexibly
generate multi-panel figures. `plotgardener` accomplishes these goals by
utilizing 1) a coordinate-based plotting system, and 2) edge-to-edge
containerized data visualization. The coordinate-based plotting system
grants users precise control over the size, position, and arrangement of
plots. Its edge-to-edge plotting functions preserve the mapping between
user-specified containers and the represented data. This allows users to
stack plots with confidence that vertically aligned data will correspond
to the same regions. For more information about plotgardener’s philosophy
and design, check out the `Our Philosophy` page.
Specialized for genomic data, `plotgardener` also contains functions to read
and plot multi-omic data quickly and easily. These functions are
integrated with Bioconductor packages to flexibly accommodate a large variety
of genomic assemblies. `plotgardener` can address an
endless number of use cases, including: dynamic exploration of genomic
data, arrangement into multi-omic layouts, and survey plotting for
quickly viewing data across the genome. Check out our `vignettes` for
detailed examples and suggested use cases!

## A word of caution
`plotgardener` is incredibly flexible and functional. However, due to this
flexibility and like all programming packages, it may not always prevent
users from making unintentional mistakes. If plot sizes are entered
incorrectly or data is mishandled, it is possible to connect multi-omic
data incorrectly. Make sure you utilize package features that reduce
human error and increase re-usability of code to get the most mileage out
of plotgardener.
