We are looking for Product Roadmap tool which is easily pluggable into Jira.

Here are the requirements :

• Good visualization for displaying : Initiatives--> Epics--> User stories --> Sprints-->Releases.
• Need good mapping between : Initiatives--> Epics--> User stories --> Sprints-->Releases.
• Easy to use and readily pluggable into Jira.
• Should support Cloud and DataCenter (since we are planning to migrate from Cloud to DataCenter)

Please suggest.
