This document provides an overview of building an immersive mixed reality experience using HoloLens and Office 365 data. It discusses using the Microsoft Graph API to retrieve people and relationship data from Office 365 and visualizing it using a force-directed graph algorithm in Unity. The steps involved include setting up a Unity project, creating a UWP DLL to access the Graph API, integrating the force-directed graph code, and implementing controller code, gaze, and gestures for interaction. The final result embeds an interactive 3D network visualization of people and relationships from Office 365 data directly into a HoloLens mixed reality experience.
