Creates a reproducible 'ggplot2' object by storing the data and calls.

Moon charts are like pie charts except that the proportions are
    shown as crescent or gibbous portions of a circle, like the lit and unlit
    portions of the moon. As such, they work best with only one or two groups.
    'gggibbous' extends 'ggplot2' to allow for plotting multiple moon charts in
    a single panel and does not require a square coordinate system.

An extension of 'ggplot2' that makes it easy to add
             raw 'grid' output, such as customised annotations, to a 
             'ggplot2' plot.

Provides one-liner functions for common legend and guide operations
    in 'ggplot2'. Simplifies legend positioning, styling, wrapping, and
    collection across multi-panel plots created with 'patchwork' or 'cowplot'.

A 'ggplot2' extension that does a variety of little
    helpful things.  The package extends 'ggplot2' facets through
    customisation, by setting individual scales per panel, resizing panels
    and providing nested facets.  Also allows multiple colour and fill
    scales per plot. Also hosts a smaller collection of stats, geoms and axis 
    guides.

Reproduce the halfnorm() function found in the 'faraway' package 
    using the 'ggplot2' API.

A Humanitarian Data Exchange (HDX) theme, color palettes, and
    scales for 'ggplot2' to allow users to easily follow the HDX visual design
    guide, including convenience functions for for loading and using the
    Source Sans 3 font.

Create hexagonal heatmaps with 'ggplot2',
    using the 'size' aesthetic to variably size each hexagon.

Make it easier to explore data with highlights.

Wrapper around geom_histogram() of 'ggplot2' to plot the histogram of a numeric vector. This is especially useful, since qplot() was deprecated in 'ggplot2' 3.4.0.

A user-friendly, highly customizable R package for building
    horizon plots in the 'ggplot2' environment.

Splits date and time of day components from
    continuous 'datetime' objects, then plots them using grammar
    of graphics ('ggplot2'). Plots can also be decorated with
    solar cycle information (e.g., sunset, sunrise, etc.).
    This is useful for visualising data that are associated with
    the solar cycle.
