Ten simple rules for designing graphical abstracts

The funders had no role in study design, data collection and analysis, decision to publish, or preparation of the manuscript. According to Cell press guidelines, graphical abstracts should inspire audiences to browse, stimulate their interdisciplinary curiosity, and allow them to rapidly screen for papers in journals [4]. The 10 rules are informed by our experience teaching biologists, clinicians, students, and established scientists, and from jointly preparing graphical abstracts for publications and grants (Fig 1). Biology and Medicine require specific icons which are available in the following repositories: * Phylopic (https://www.phylopic.org/) offers shapes of numerous animals, plants, and further model organisms, e.g., for phylogenetic trees. * The EBI (https://www.ebi.ac.uk/style-lab/general/fonts/v1.3/) provides some general scientific icons. * Reactome (https://reactome.org/icon-lib) provides scientific pictograms and chemical drawings for free re-use and encourages the upload of user-designed pictograms for sharing with the scientific community. * Smart (https://smart.servier.com/) is a free collection of medical drawings from Servier Medical Art and can be downloaded as a full slide-deck and used with attribution. * Bioicons (https://bioicons.com/) is an expanding set of biology and laboratory icons from Petri dishes to model organisms available under free licenses (CC0).
