Over the last six months we have been working with a group of scientists, including the VIZBI speakers and others, to prepare a series of reviews on visualizing biological data. Today these reviews have been published in a supplementary issue of Nature Methods (Volume 7 No 3 ppS1-S68). In addition to five reviews covering visualization of data from systems biology, genomics, 3D macromolecular structures, alignments and phylogenies, and image-data, the supplement also contains a commentary on future visualization. The editors have also written a 1-page forward and 2-page summary of all reviews. Thanks again to Bang Wong for help with the cover image. We have written the reviews to be understandable to beginners as well as credible to experts. We believe this collection will be a valuable resource for the community of life scientists using visualization as part of their research.
