D3 Visualization with CodeIgniter

I need a web application for a demo that uses MongoDB as a backend (I will send sample data) and on the front end shows something similar to this below. [login to view URL] * Has to be clickable so that when you click a node, it stays * Save a certain set of data (selections on the UI) as a "key" * Load a data set based on that key * Delete/copy data set to new key Also, when there's data, there's need to be a column on the left that shows "matching keys"... as you select things on the UI, those keys will narrow down to only show things that have those particular selections. Will be required to sign NDA.
