Plotly figures get formed nodes are articulation points will increase the number of components. In graph theory, a component of an undirected graph is an induced subgraph in which any two vertices are connected to each other by paths, and which is connected to no additional vertices in the rest of the graph.For example, the graph shown in the illustration has three components. Using example code on documentation page ( ).These examples are extracted from open source projects get strongly. The list is ordered from largest connected component to smallest.
