The most isolated community is determined by computing the Graph Distance metrics. Specifically, the community with the lowest median Closeness Centrality is the most isolated community.
The most isolated community is weakly connected to the other communities in the network. This implies that the nodes in the community are niche or not alike the other nodes and communities of the network in some way.
When you select this insight, the most isolated community will be highlighted and the other nodes/edges will be dimmed. Furthermore, any edges that exist amongst the nodes in the most isolated community will be highlighted in gold (edge highlight color). This will help to interpret the layout of the most isolated community in relation to the rest of the network.
