Diagram of the ggbio framework for processing sequence data. It starts with a mapping from different file types to different objects or data structure in R, using Bioconductor tools, followed by general and extended grammar of graphics mapping of data elements to graphical components. The final stage arranges the graphics in a designed layout to show annotation tracks or multiple data sets. Orange boxes and dark brown arrows indicate the extensions provided by ggbio.
