WHAT IS CIRCOS?

THIS IS A NICE DATA VISUALIZATION TOOL THAT IS OPEN SOURCE.

CIRCULAR VISUALIZATION
Circos is a software package for visualizing data and information. It visualizes data in a circular layout — this makes Circos ideal for exploring relationships between objects or positions. There are other reasons why a circular layout is advantageous, not the least being the fact that it is attractive.

Circos is ideal for creating publication-quality infographics and illustrations with a high data-to-ink ratio, richly layered data and pleasant symmetries. You have fine control each element in the figure to tailor its focus points and detail to your audience.

▴ Images created with Circos, illustrating links, ribbons, tiles and a variety of 2D data tracks. If it’s round, Circos can probably do it (more images).
Circos is flexible. Although originally designed for visualizing genomic data, it can create figures from data in any field. If you have data that describes relationships or multi-layered annotations of one or more scales, Circos is for you.

Circos can be automated. It is controlled by plain-text configuration files, which makes it easily incorporated into data acquisition, analysis and reporting pipelines (a data pipeline is a multi-step process in which data is analyzed by multiple and typically independent tools, each passing their output as the input to the next step).
