LO Network Visualisation Techniques. Techniques for the integrated visualisation of lifespan experiments as networks. LOs and AFs are represented by nodes. Node colour and size are used to speed-up the lookup of node properties by visual perception. a DirectNeighbourhood: For focusing on a specific AF only the direct neighbourhood of the AF is visualised. This includes the AF in the focus (AF₁), all directly linked LOs (LO₁,LO₂,LO₃), and all other AFs linked directly to these LOs (AF₂,AF₃). b Complete Neighbourhood: For a more comprehensive view the direct neighbourhood network is extended iteratively by including further AFs (AF₄,AF₅) that were observed together with the neighbours (AF₂,AF₃) of the AF in the focus (AF₁) and their LOs (LO₄,LO₅,LO₆,LO₇,LO₈). c Augmentation via Annotation Nodes: Additional information for AF and LO nodes is integrated by annotation nodes (ANN₁, ANN₂). They provide the information directly in a visual form and result in a reorganisation of the network layout. d Data Transfer between nodes: The data transfer between nodes can help to reduce the complexity of a network by removing nodes while retaining some of their data. Here all 8 LOs were removed after transforming the directions of the lifespan changes into a new colour scheme for the 5 AFs. e Multi-species: A special case of essential augmentation with species nodes for networks focusing on AFs that can be linked to multiple species, like chemical compounds. For a clearer view the AFs are linked only indirectly to the species nodes by the LOs: AF₁ to SP₁ via LO₁, to SP₂ via LO₂, and to SP₃ via LO₃ and LO₄;AF₂ to SP₁ via LO₁;AF₃ to SP₃ via LO₄. Color scheme (a, b, c, e): AF, LO - increased lifespan, LO - decreased lifespan, annotation, species Color scheme (d): annotation, AF - linked only to LOs with increased lifespan, AF - linked to LOs with highly mixed lifespan changes (increased and decreased >20%)
