| links = links.filter(l => l.source !== node && l.target !== node); // Remove links attached to node | |
| nodes.splice(node.id, 1); // Remove node | |
| nodes.forEach((n, idx) => { n.id = idx; }); // Reset node ids to array index | |
| Graph.graphData({ nodes, links }); | |
| } | |

How do I achieve const { nodes, links } = Graph.graphData(); for ReactForceGraph2d?
