A radial tree visualization displays hierarchical operations data, with each node representing a mission phase or component. The layout arranges nodes around a circular structure, using rotated text labels. The code employs `d3.stratify()` to convert flat CSV data into a hierarchy and `d3.tree()` with a custom `project()` function to map Cartesian coordinates to radial positions. Curved link paths connect parent and child nodes, while rendered SVG elements distinguish internal and leaf nodes. The visualization reads from `operations.csv` and uses D3 v4 within a React-based setup.
