This graph diagram visualizes the network of connections among concepts like Federated Learning, Edge Computing, and Machine Learning, using node size to distinguish main, child, and leaf nodes. It shows the relationships between these topics through linked nodes and colored edges. The visualization uses d3.forceSimulation with forceManyBody, forceLink, and forceCenter to compute the layout, while drag interactions allow manual repositioning. Node and link data are defined in data.js, with colors sourced from colors.js, and the scene is rendered as SVG circles, lines, and text labels.
