circle_genomic() constructs a circular layout specifically for genomic
data. It is a specialized variant of circle_continuous() that applies
default axis limits and coerces the first column of each plot's data to use
chromosome (seqname) identifiers-matching those in the layout data-as
factor levels.

)A circle_layout object representing the genomic layout.
The input data, which can be:
A character string ("hg19" or "hg38") to load a predefined cytoband
reference.
A data.frame with at least three columns: chromosome, start, and
end positions.
A genomic object convertible via fortify_data_frame().
Additional arguments passed to specific methods or
fortify_data_frame().
A coord_circle()/coord_radial()
object that defines the global parameters for coordinate across all plots
in the layout. The parameters start, end, direction, and expand will
be inherited and applied uniformly to all plots within the layout. The
parameters theta and r.axis.inside will always be ignored and will be set
to "x" and TRUE, respectively, for all plots.
A single string of "inward" or "outward",
indicating the direction in which the plot is added.
outward: The plot is added from the inner to the outer.
inward: The plot is added from the outer to the inner.
The size of spacing between different panel. A numeric
of the radians or a rel() object.
A theme() object used to customize various
elements of the layout, including guides, title, subtitle, caption,
margins, panel.border, and background. By default, the theme will
inherit from the parent layout. It also controls the panel spacing for all
plots in the layout.
