研究方向

First, examine the codebase to understand how nodes are added, likely in a file like 'graph.js' or 'cluster.js'. Look for functions that create or insert nodes. Refer to issue #117 for context on duplicate errors. Implement a simple check using a JavaScript Set or object to track existing node IDs. Before adding a node, verify that its ID does not already exist. Test the change by attempting to add a duplicate ID and confirm it is ignored. If the project uses a framework (e.g., D3.js), ensure the logic integrates correctly.
