Removed Comments below:
“ Change the APIs vizEngine_ parameter if you wish to use a different
visualization library. Returns the generated graph objects in form of a
python list. One may use the returned objects to modify the graph
properties.”

..COMMENT: The above hyperlink should direct the user to the API methods page.

“ exportDataFlag: boolean, default: False
If True, the graph data points are stored on the local machine. The export path and file format are set by the APIs parameters_.”
..COMMENT: I believe you want the hyperlink above to direct user to the API methods page.
