# Given an output filepath and one or more tabular datafile inputs, render
# the visualization of the input datafiles.
# @param output_filepath [String] location where the output file should be
#                              written.  Note, if the file already exists it
#                              will be overwritten.  Note that the file
#                              suffix indicates the output format that will
#                              be used.  Valid extensions are: jpg, dot, gif,
#                              svg, png, json, pdf
#            
# @param input_filepaths [Array<String>] One or more input files.  Note that the
#                              program will take a best guess at the text file
#                              format with file suffix (csv, tsv) being the
#                              a strong signal.  The order of the filenames
#                              is used as their load order.
