Parameters
----------
data_source : <Problem> or str
The Problem or case recorder database containing the model or model data.
outfile : str, optional
The name of the final output file
show_browser : bool, optional
If True, pop up the system default web browser to view the generated html file.
Defaults to True.
embeddable : bool, optional
If True, gives a single HTML file that doesn't have the <html>, <DOCTYPE>, <body>

title : str, optional
The title for the diagram. Used in the HTML title.
