In 2010 Laszlo Hanyecz paid 10K BTC for two pizzas. If you want to investigate this story go directly to the original post he wrote on the Bitcointalk forum.

The visualization tracks the origins of the coins used in the transaction up to their coinbase.  I made it using python, Blockstream API and Pygraphviz.

The green color marks all the coinbase transaction. The blue color was used to show amounts above 100 BTC and orange above 1000 BTC.
Names of the graph's nodes were derived from the hex representation of the last two bytes of the transaction hashes.
