[circos-basic] Circos Plot for Circular Genome or Relationship Visualization

[MarkusNeusinger]

A Circos-style circular plot for visualizing relationships, connections, or genomic data. Features concentric tracks arranged in a circle with ribbons or arcs connecting related elements.

[claude]

✅ Spec ID: circos-basic

Rationale: Circos plots are an established visualization type specifically designed for circular genome visualization with concentric data tracks and connecting ribbons. While chord-basic exists, it focuses solely on connections between entities, whereas Circos plots emphasize the multi-track circular layout commonly used in bioinformatics.

Add label approved to begin generation.

circos-basic: Circos Plot

Description

A Circos plot is a circular visualization that displays data on concentric tracks arranged around a circle, with ribbons or arcs connecting related segments across the circular layout. Originally designed for genomic data visualization, it excels at showing relationships between segments while simultaneously displaying multiple data attributes on different tracks. The circular arrangement makes efficient use of space and reveals patterns in complex relational data.

Applications

• Visualizing chromosomal rearrangements and genomic structural variations in bioinformatics
• Displaying trade flows or migration patterns between countries or regions
• Showing dependencies and relationships between software modules or system components
• Analyzing co-occurrence or correlation patterns between categorical variables

Data

• source (categorical) - Origin segment or category identifier
• target (categorical) - Destination segment or category identifier
• value (numeric) - Connection strength or flow magnitude between segments
• segment_size (numeric, optional) - Size of each segment on the outer ring
• track_data (numeric, optional) - Values for additional concentric data tracks
• Size: 5-30 segments with 10-100 connections
• Example: Genomic data showing 10 chromosomes with inter-chromosomal connections and expression values on inner tracks

Notes

• Segments should be arranged around the circle with gaps for visual separation
• Ribbon width should be proportional to the connection value
• Use distinct colors for each segment to aid identification
• Consider adding 1-3 concentric tracks inside the outer ring for additional data layers
• For genomic applications, segments typically represent chromosomes with consistent color coding
