How can this graph describe why water can be 100 degrees Celsius and still be water?

Water will continue rising in temperature after reaching 100 degrees C, while it is turning into a gas.

Once the water reaches 100 degrees C, it will immediately turn into a gas

This graph is incorrect. The moment water reaches 100 degrees Celsius, it turns into a gas

Once water is 100 degrees Celsius, it needs extra energy, in the form of heat added, to finish turning into a gas. Once a gas, it can continue gaining temperature as it gains heat. Otherwise, the water in the system will remain 100 degrees until that point.
