Hi Sanjukta,
Thank you for your response.
Here are the answers to your questions:
1) Fusioncharts.js is in the <head> tag
2) We have both ways in our application - where chart gets rendered before the browser page is loading and also where we just have a link which open up a new window that renders the chart
3) Not sure about this - how to check about the DOM
Please let me know if you need more info.
Thanks,
Rekha
