Data visualization is a technique for data representation in the form of tables, charts and diagrams. This article explains representation of demographic information of the participants (e.g. teachers) based on nodes in Nvivo.

Mind maps portray the connection between nodes. Concept maps on the other hand help visualise thoughts, define concepts and contemplate the connections.

Mind maps are used to brainstorm ideas and visualize thoughts. A mind map begins with a main idea around which associated elements are drawn. They are useful for representing a node hierarchy.

This article explains qualitative data representation in NVivo. Visualisation takes place on attitudes or perceptions of participants on certain issues. With the use of different tools, visualisation takes place on different qualitative items of projects.

Cluster analysis serves as an extension to qualitative data representation through data visualisation. It is an exploratory technique for visualising patterns in a study by grouping sources or nodes.
