Visualisation

Visualisation is when data or concepts are presented in simpler form for humans to understand
It will often create a graphical or visual representation of something to understand complex systems or data

Benefits	Drawbacks
Visualisation can simplify concepts that are easier for humans to understand.	Although it can show data in a visual way, it cannot explain why something is the way that it is.
It can make it easier to spot new trends and patterns that have not been spotted before.	Different people may interpret the visualisations in different ways.
It can be used to explain complex situations to allow programmers to get a better understanding of the problems of a current system.	The way that the data is presented can have an impact on its understanding.
