Epigenomics is the study of genome-wide distributions of chromatin modifications. Our knowledge of epigenomics has drastically improved with next-generation sequencing (NGS) with techniques like whole-genome bisulfite sequencing (WGBS) and chromatin immunoprecipation sequencing (ChIP-seq). With the large quantities of data being produced, data visualization is an important step for quality control and exploration.
Numerous software programs exist to visualize genomics data; most popular is the genome browser. These existing programs focus on a limited subset of data types such as mRNA-seq and single-nucleotide polymorphisms.
