Add functionalities on an existing D3JS app

We already have a D3JS application based on the Force Layout visualisation, similar to [URL visible pour les membres Pro]

This application needs to be improved to add the following functionalities:

- The nodes should not be repulsed by the border of the visualisation

- Longer labels should always be displayed and they should not overlap: for example they can be positioned using a force placement (see following link: bl.ocks.org/MoritzStefaner/[Téléphone visible pour les membres Pro])

Example of label:
Name Surname – Age
Text aaaaa – text b
Text CCCCCCC

- On right click on a node, all the other nodes corresponding to a given criteria should be highlighted (highlight: add a red border on corresponding images).

- Some buttons are currently available on the application; we will need a collapsible panel to store them. See ‘Collapsible Panel’ in the following link: [URL visible pour les membres Pro]
