save https://www.google.com/jsapi as a my.js file(copy-paste with some text editor) on the same folder as your html and replace
<script type='text/javascript' src='https://www.google.com/jsapi'></script>
with
<script type='text/javascript' src='my.js'></script>
This would not work
first Google do not permit this
secondly if you copy paste it would not work
as jsapi file generates a file like google/udc/?vi.... referencing locally will not work if you
add <script type='text/javascript' src='my.js'></script>
it will generate file my.js/?vi....'
and it would not load (404 Not Found) if you remove .js extention
I't not possible to use google charts offline. Legaly impossible.
I made an organizational chart using Jit js, and you can use it offline.
