Visualizing co-phylogenetic reconciliations
We introduce a hybrid metaphor for the visualization of the reconciliations of co-phylogenetic trees, that are mappings among the nodes of two trees. The typical application is the visualization of the co-evolution of hosts and parasites in biology. Our strategy combines a space-filling and a node-link approach. Differently from traditional meth- ods, it guarantees an unambiguous and ‘downward’ representation when- ever the reconciliation is time-consistent (i.e., meaningful).
