Adding Timeline to Google Site

I came across a Timeline which can be embedded in the Google site. Check the video here.

Reference: http://timeline.knightlab.com/

I followed the exact steps as per the video. However the timeline was not being displayed in the Google site. On digging further in the issue I found out that Google doesn't allow the http pages in the iFrame.

The solution is to convert the http to https page as follows:

Replace the "http://cdn.knightlab.com/libs/timeline/latest/embed" in the url with "https://s3.amazonaws.com/cdn.knightlab.com/libs/timeline/latest/embed".
