Click to add nodes! Nodes near the cursor will be linked to the new node.
D3's force layout uses the Barnes–Hut approximation to compute repulsive charge forces between all nodes efficiently. Links are implemented as geometric constraints on top of position Verlet integration, offering greater stability. A virtual spring between each node and the center of the chart prevents nodes from drifting into space.

| 1. Have two pointers ptr1 and ptr2 pointing to head of linked list | |
| 2. Traverse one pointer say ptr2 to distance n from head | |
| 3. Now, traverse both | |
| 4. When ptr2 reaches the tail, ptr1 is at distance "n" from the tail of linked list | |
