Graphs can be a powerful way to represent relationships between data, but they are also a very abstract concept, which means that they
run the danger of meaning something only to the creator of the graph … Everything looks like a graph, but almost nothing should ever be
drawn as one.
Ben Fry in ‘Visualizing Data’

Explanatory visualizationData visualizations that are used to transmit information or a point of view from the designer to the reader. Explanatory visualizations typically have a specific “story” or information that they are intended to transmit.
Exploratory visualizationData visualizations that are used by the designer for self-informative purposes to discover patterns, trends, or sub-problems in a dataset. Exploratory visualizations typically don’t have an already-known story.
