An animated chord diagram visualizes the 2021 service-group interactions for ICTS, using a 31-by-31 matrix of numeric values to represent relationships between named internal domains and support teams. The visualization uses D3 v3 to render the circular layout, with chord paths displaying connection strengths and the matrix defining the data source for all links. The example employs D3’s chord layout and animation to display the flow of interactions, with hover states and title text providing context for each group.
