Abstract
Genome browsers that manage, communicate and visualize data have greatly facilitated genomics research. Here, we present an open-source programming library, called GIVE library, that allows anyone with HTML programing experience to build custom genome browser websites or apps. With a few lines of codes, one can add to a personal webpage an interactive genome browser that host custom data. This portable library encapsulates novel data communication and data visualization technologies, including new data structures and new memory management methods, that enable efficient data transfer between the data-hosting website and internet browsers.
