Circos plots

Definition

Circos plots are a visualization technique used to represent complex genomic data in a circular layout, highlighting relationships between multiple data types. They integrate various layers of information, such as genomic features, gene expression, and epigenetic modifications, facilitating the exploration of multi-omics datasets in systems biology. By providing a comprehensive overview of interconnected data, circos plots help researchers identify patterns and correlations that might be missed with traditional linear representations.
