Information and data come with different shades of meanings and degrees of complexity. Some forms of data require a higher level of understand and therefore tend to be more complex and abstract. Hence the important of visual aids in facilitating the communication of complex messages.

Graphs and charts are two examples of popular constructs we use to visualize interconnections and simplify meanings (concept mapping tools are also equally important). As teachers and educators, we often have recourse to these visual aids to help us communicate in a more effective and comprehensible way.  Graphs and charts are also great for turning dense information into digestible visuals.  

What are graphs and charts? 

Graphs and charts are visual representations of data. They are basically used to capture the interrelatedness of the elements making up a set of data. However, graphs are different from charts and each one of them is used to represent a particular genre of data. 

According to Indeed, ‘charts are tables, diagrams or pictures that organize large amounts of data clearly and concisely. People use charts to interpret current data and make predictions. Graphs, however, focus on raw data and show trends over time.’
