When Data Visualization Works — And When It Doesn’t
data visualization is about communicating
an idea that will drive action.
Harvard Business Review MARCH 27, 2013 “When Data Visualization Works — And When It Doesn’t”
the reasoning behind constructing data visualizations will help you do that with efficiency and impact.
Harvard Business Review MARCH 27, 2013 “When Data Visualization Works — And When It Doesn’t”
For information to provide valuable insights,
it must be interpretable, relevant, and novel.
Harvard Business Review MARCH 27, 2013 “When Data Visualization Works — And When It Doesn’t”
Collecting lots of data without the associated metadata reduces the opportunity
to play with, interpret, and gain insights from the data.
Harvard Business Review MARCH 27, 2013 “When Data Visualization Works — And When It Doesn’t”
It must also be relevant to the persons who are looking to gain insights, and to the purpose for which
the information is being examined.
Harvard Business Review MARCH 27, 2013 “When Data Visualization Works — And When It Doesn’t”
it must be original, or shed new light on an area. If the information fails any one of these criteria, then no visualization can make it valuable.
Harvard Business Review MARCH 27, 2013 “When Data Visualization Works — And When It Doesn’t”
There are three broad reasons for visualizing data
Harvard Business Review MARCH 27, 2013 “When Data Visualization Works — And When It Doesn’t”
Confirmation: If we already have a set of assumptions
about how the system we are interested in. visualizations can help us check those assumptions.
Harvard Business Review MARCH 27, 2013 “When Data Visualization Works — And When It Doesn’t”
Education: One is simply reporting. The other is to develop
intuition and new insight.
Harvard Business Review MARCH 27, 2013 “When Data Visualization Works — And When It Doesn’t”
Exploration: We can use visualization to help
build a model to allow us to predict and better manage the system.
Harvard Business Review MARCH 27, 2013 “When Data Visualization Works — And When It Doesn’t”
what gives us confidence that these insights are now worthy of action?
Harvard Business Review MARCH 27, 2013 “When Data Visualization Works — And When It Doesn’t”
Data quality: The quality of the underlying data is crucial to the value of visualization.
How complete and reliable is it?
Harvard Business Review MARCH 27, 2013 “When Data Visualization Works — And When It Doesn’t”
Context: The point of visualization is to make large amounts of data approachable so we can apply our evolutionarily honed
pattern detection computer to draw insights from it.
Harvard Business Review MARCH 27, 2013 “When Data Visualization Works — And When It Doesn’t”
To leave out any contextual information or metadata (or more appropriately, “metacontent”) is to risk hampering
our understanding.
Harvard Business Review MARCH 27, 2013 “When Data Visualization Works — And When It Doesn’t”
Biases: The creator of the visualization may influence the semantics of the
visualization. any of which can challenge the interpretation of the data.
Harvard Business Review MARCH 27, 2013 “When Data Visualization Works — And When It Doesn’t”
This also creates the risk of “pre-specifying” discoverable features and results via the embedded algorithms used by the creator.

Visualizing Algorithms Mike Bostock
Bostock demonstrated processes and patterns in a wide array of algorithms for sorting, sampling, and maze generation.
The result was a useful learning resource and an appreciation for something that's otherwise a challenge to imagine for most people.
