Reporting tools StorageScope, SRM etc

Hi I am trying to configure some simple reports for management. In a nutshell I would like to generate an html file which would be emailed to selected individuals which I already do.

What I require is a report which shows ie pie chart with used disk_group info and unused disk_group info.

Everything I try so far only generates reports with so much in-depth information that the reports are totally useless to people like myself who only require broad scope information to make capacity recommendations.

Any help would be greatly appreciated
