Hi Rakesh,
If you are implementating SAS Visual Investigator on a Site for your company or a customer, you can have answers to most of your question from the product documenation. I've given you the links below. The steps have been explained with examples. In case you don't have access to the links below and need an access key, contact the SAS Tech Support for your Site specific Key.
You can have a look at the link below:
https://support.sas.com/en/software/visual-investigator.html
The tutorials have been broken into individual sections -- under scenario authoring, data, page and object manager configuration, and more for your specific questions.
You can also look at the link below:
http://support.sas.com/documentation/prod-p/visgator/index.html
for the 4 sections: 1) Getting started, 2) User's Guide, 3) Administrator's Guide and 4) Using the Scenario Administrator
Hope this helps.
Regards,
Ankur Biswas
