Why is Segwit in the first picture? It didn't create a chain split, it was a protocol upgrade for Bitcoin. You start to mix up things when you try to talk about forked coins, then switch to software forks - Bitcoin had many more hard and soft forks that didn't create new cryptocurrencies.

Also, there's a ton of coins from early days that didn't fork Bitcoins blockchain and started from their own genesis block, but had very similar code to Bitcoin, so they too can be considered Bitcoin forks in a sense that they were software forks.
