If you look into RFCs, you will see many are updated or obsoleted. I wondered how many are as such.
I wrote a simple python code, which fetches and parses the RFC Index, and creates a simple json file.
Then, I made a simple matrix visualization with d3.js where a cell represents an RFC, and below there are 8394 RFCs. Keep in mind this page is not live, it is a snapshot taken on 14 December 2018.
In the visualization:
- red shows the obsoleted RFCs
- blue shows the updated RFCs
- green shows all other RFCs
