I would like to visualize gene fusions in a way that illustrates the gene structure (primarily exons) of belonging to the normal gene partners and how they are joined to form the fusion (similar to the figure below). For a few events, I could draw this manually, but I'd like to create figures for hundreds of fusion events. Are there free or commercial tools available for this? I know people have typically visualized fusion events in IGV or using circos plots (e.g. FusionAnalyser), but this is not exactly what I'm looking for. Thanks.
