I feel like going to the source of an algorithm/implementation is a super power, as illustrated by this example.

Having used Graphviz for fairly complex visualizations I was initially shocked that someone would rewrite it themselves. Then I saw the breakdown of the algorithm and realized it may not be as complicated as I first thought.

All that being said, as a general rule it is hard to know what the hidden complexities may be until you are finished implementing the algorithm.
