In these graphs, address reuse is highlighted by grey edges from inputs/outputs to inputs/outputs. Below I have highlighted the address reuse edges in red, showing some of my first transactions using bitcoin.

In the three leftmost transactions I am receiving bitcoin from Circle to my address, and in the rightmost I am spending bitcoin from my address on Steam via BitPay.

General address reuse will appear as grey edges in the network graphs.
