The project structure consists of JavaScript functions and optimizations for creating and managing nodes and links in a D3.js graph.
The edgeEnter function is responsible for creating new nodes as they enter the graph. It constructs the visual representation of a node with various attributes, such as color, text, and actions. This function is part of the code responsible for rendering nodes.
The edgeUpdate function updates existing nodes with new data. It is responsible for handling changes in the positions of nodes within the graph.
The edgeExit function removes nodes when they exit the graph. It takes care of cleaning up elements that are no longer needed.
The edgeDragging function allows nodes to be dragged and moved within the graph. It is responsible for updating node positions when they are dragged.
The dragLineListener function handles the creation of lines connecting nodes while dragging. It also supports linking nodes together when the drag operation is completed.
The pathEnter function is responsible for creating new path elements to represent links between nodes as they enter the graph. It constructs the visual representation of links, including styling and markers.
The pathUpdate function updates existing path elements with new data. It is responsible for handling changes in link positions and attributes.
The pathExit function removes path elements when links exit the graph. It takes care of cleaning up elements that are no longer needed.
The createPath function generates a path description for the links between source and target nodes. It calculates the coordinates and structure of the link path.
