Add google org chart to wordpress page

The fastest way would be an iframe plugin ( like “Embed Iframe”) , you can then just copy past it all and cross your fingers.

You might also be able to just copy/past from the script tag to /script into the html editor of a post.

The alternative and best method is to make your own custom template page and throw it into the source code using wp enqueue script.
