For those more complex datasets, there are a range of more elaborate data visualizations at your disposal—network graphs being one of them. Network graphs show how different elements or entities within a network relate to one another, with each element represented by an individual node. Both types of visualizations generally require software to create, as the most effective visualization will draw from several data sources. Whereas data scientists do most of the work on visual exploration, managers do most of the work on everyday visualizations. This quadrant comprises the basic charts and graphs you normally paste from a spreadsheet into a presentation.

Discovering a channel that’s under- or over-performing gives leadership the signal to investigate further and identify a potential gold mine or deadweight. For example, a company may conduct a study on employee engagement and use an infographic to walk through numerous stats from the study in visual form.

Data visualization is the presentation of data in a pictorial or graphical format. It enables decision makers to see analytics presented visually, so they can grasp difficult concepts or identify new patterns. Better hardware has meant more precise reproduction, better color (including alpha-blending), and faster drawing.
