A circular node-link diagram arranged by a hierarchy, with edges bundled using D3's `d3.lineRadial` and `d3.curveBundle` to show connections between food-related entities. The chart, rendered as an SVG, draws food nodes from `food_nodes.csv` and edges from `food_edges.csv`, coloring links orange on hover to highlight a selected node's relationships. A slider adjusts the tension of the bundled curve, interactively reshaping the edge paths. The data, attributed to “Xhy51”, likely represents a network of food brands and chefs.
