How to implement charts and reports in Oracle

I want to implement charts and reports on oracle in my project.  What are the options available in oracle? I explored that it supports the high end charts for dashboard from data ware house? How can I implement that? My project caters to the need of sales team. Is there any other functionality which can build 3D charts in oracle? Also I need to attach audio and video in the charts to self-demonstrate the use of project. Can someone help me on that?
