circHiC: circular visualization of Hi-C data and integration of genomic data

circHiC is a Python library, built upon the widely used Matplotlib library, to display Hi-C-like data in circular strips together with the possibility to overlay genomic data (plots and heat maps). Tools are light and fast, aiming to facilitate the exploration and understanding of bacterial chromosome structuring data.

Genome wide contact frequencies obtained using Hi-C-like experiments have raised novel challenges in terms of visualization and rationalization of chromosome structuring phenomena. In bacteria, one difficulty consists in displaying data in a way that is congruent with the circularity of chromosomes. Standard representations of Hi-C data under the form of square matrices or horizontal bands are indeed not adapted to periodic conditions as those imposed by (most) bacterial chromosomes. circHiC fills this gap.
