  We design and evaluate a novel layout fine-tuning technique for node-link
diagrams that facilitates exemplar-based adjustment of a group of substructures
in batching mode. The key idea is to transfer user modifications on a local
substructure to other substructures in the whole graph that are topologically
similar to the exemplar. We first precompute a canonical representation for
each substructure with node embedding techniques and then use it for on-the-fly
substructure retrieval. We design and develop a light-weight interactive system
to enable intuitive adjustment, modification transfer, and visual graph
exploration. We also report some results of quantitative comparisons, three
case studies, and a within-participant user study.
