Create a chord diagram visualization of CellPhoneDB interactions.

Parameters:

  • adata (AnnData) – Annotated data object with cell type information

  • interaction_edges (DataFrame) – DataFrame with SOURCE, TARGET, and COUNT columns

  • celltype_key (str) – Column name for cell type annotation

  • count_min (default: 50) – Minimum interaction count threshold (50)

  • nodecolor_dict (default: None) – Custom color mapping for cell types (None, uses default)

  • fontsize (default: 12) – Font size for labels (12)

  • padding (default: 80) – Padding around chord diagram (80)

  • radius (default: 100) – Radius of the chord diagram (100)

  • save (default: 'chord.svg') – File path to save SVG output (‘chord.svg’)

  • rotation (default: 0) – Rotation angle for the diagram (0)

  • bg_color (default: '#ffffff') – Background color (‘#ffffff’)

  • bg_transparancy (default: 1.0) – Background transparency (1.0)

Returns:

OpenChord figure object

Return type:
