Dynamic navigation help/ideas

Hiya,

I have been asked to create a dynamic navigation system that will take data from an Oracle database then generate a navigation path based on data retrieved from the backend.

The diagram below is an example of what one of these paths could look like, any bigger and it would continually snake from left to right.

My skills are in html, css & jquery, would these skills be enough to complete such a task? Do any of you guys have any better idea of what technology could be used? Better still any of you know of any examples of something remotely similar to this being done before?

Any help appreciated.
