The 'Vega-Lite' 'JavaScript' framework provides a higher-level grammar
for visual analysis, akin to 'ggplot' or 'Tableau', that generates complete 'Vega'
specifications. Functions exist which enable building a valid 'spec' from scratch
or importing a previously created 'spec' file. Functions also exist to export 'spec'
files and to generate code which will enable plots to be embedded in properly
configured web pages. The default behavior is to generate an 'htmlwidget'.
