Hey, I have found the paper you recommended about data visualization. It is very easy for me to understand that how to visualize the quantitative data, but qualitative? I mean how could our project visualize the interview? It sounds too difficult.

Glad to hear.

Oh, I understand it now. Many thanks!

Right and wrong. Actually, qualitative data are broad in scope and can take the form of transcribed interviews, recorded conversations among stakeholders, pictures, videos, or drawings that capture events, processes, and outcomes. Each of these data types could adopt unique approaches and methods of visualization to optimize the knowledge that they contain.
