`plot_data`	a dataframe with all the plotting information
`x`	the column containing x coordinates, similarly for `y` and `z`
`all_theta`	the degree of azimuthal (horizontal) rotation
`all_phi`	the degree of vertical rotation
`show_axes`	whehther to show 3D axes
`show_arrow`	whether to show 3D segments (arrows)
`show_label`	whether to show text labels
`label_col`	which column contains the label information
`num_col`	number of columns for `facet_wrap`
`axis_length`	the proportion that the arrow axis occupies on the entire axis
`lab_just`	adjust the labels of the arrow axes radially. You may supply one value for all 3 axes, all 3 values for x, y and z axes respectively
`vert_just`	adjust the labels of the arrow axes vertically
`further_repel`	if TRUE, the labels would be repelled away from the data points as much as possible
`size_highlight`	a character, logical or numeric vector specifying which cells to magnify in size
`highlight_ratio`	how much larger the highlighted cells should be
`AP`	aesthetic parameters controlling arrow appearance
`force_repel`	extent of repulsion
