I had originally written this app with object of learning the APIC data model which was helpful with REST and with actually understanding the connectivity within the model itself. I have tided it up recently (to a lesser degree ) and wanted to share it with others as I started to find it useful when writing scripts to find MO's and contained attributes or just make sure I had the model path correct. The model viewer is written in JS with D3JS. Its hosted at github at GitHub - simonbirtles/aci-model-viewer: Cisco ACI APIC Model Viewer
