circlize

circlize generates customizable circular visualizations to represent genomic and multi-dimensional biological data relationships.

Key Features:

• Circular Layout Generation: Transforms large genomic and multi-dimensional datasets into circular layouts to represent relationships and patterns that are difficult to discern in linear formats.
• Low-Level Graphics Functions: Implements R low-level graphics primitives as the foundation for constructing custom visual elements.
• Custom High-Level Graphics: Enables creation of tailored high-level graphics by composing the provided low-level functions.
• Integration with R Computational and Graphical Environment: Integrates visualization functions within R to combine computational processing and graphical rendering in analysis workflows.

Scientific Applications:

• Genome Mapping: Visualizes genomic features and inter- and intra-chromosomal relationships within circular genome maps.
• Comparative Genomics: Represents synteny, rearrangements, and relationships between genomes in a circular layout for comparative analysis.
• Multi-dimensional Biological Data Analysis: Displays multi-dimensional biological data around a circle to reveal complex patterns across datasets.

Methodology:

Builds circular plots using R's graphical capabilities and low-level plotting functions as primitives, allowing composition of custom high-level graphics.
