This interactive arc diagram visualizes correlations between financial instruments, with nodes positioned along a horizontal axis and arcs connecting correlated pairs. The visualization uses D3.js v7 within a React framework, rendering as an SVG. It employs custom D3 modules like `d3.arcDiagram` for layout and `d3.scalePoint` for positioning, while user interactions highlight connections and labels. Data is loaded from a JSON file via `d3.json`, and the code builds both a node list from unique parent and child values, and links with source/target references.
