Expression landscape and orthologous circRNAs in six vertebrates. a The number of samples and identified circRNAs in each species. The colored circles on the top panel represent different tissues. The plots in gray and blue colors represent the number of samples and identified circRNAs, respectively, in each tissue. b An UpSetR visualization of the intersection between sets of orthologous circRNAs. The grid along the bottom has been used to identify intersecting sets (analogous to a Venn diagram). The horizontal bars on the left show the total number of circRNAs detected in each species. The black dots indicate different patterns of sharing between different species, and the vertical bars represent the number of orthologous circRNA pairs for a given pattern
