EvoLaps transition diagram. a Phylogenetic tree color encoded given a set of clusters: locations (latitude/longitude) of each node (ancestral or sample) of the phylogenetic tree are linked to one cluster/color defined by the user during the analysis (gray squares, red circles and gold diamonds), b transition diagram, ‘straight’ version. A node is created in the transition diagram for each transition observed in a top-down reading of the phylogenetic tree (with the exception of the root). c Transition diagram, ‘compressed’ version. The ‘compressed’ version of the transition diagram displays similar transitions when they share the same father node in the ‘straight’ version of the transition diagram, d tree-like graphical representation of the transition diagram, several layouts, nodes size may reflects the Sz criterion: the number of tips being in the same geographic cluster along the evolutionary path from a transition to its tips. Sz values are added in the compressed version of the transition diagram for the nodes sharing a geographic cluster at the same generation (red node), e top-down reading of the transition diagram to produce paths between clusters on the geographic map. Size and curvature of the paths may reflect the generation of the transition
