Conceiving and Reasoning Visualization Design Options - Data Visualization: A Successful Design Process - page 106

As discussed in the first chapter, a key objective for effective data visualization
design is the facilitation of accessibility into a subject through intuitive design.
The degree of accessibility is enhanced through the effective inclusion of useful
explanation across all features of your visualization solution. We shouldn't assume
that readers or users are instantly and easily going to be able to navigate their way
around our designs and so we need to carefully consider the best ways to assist
them; explained as follows:
• Titles : A compelling title can help to attract an audience and articulate
the focus of the visualization subject matter. Sometimes, especially in
explanatory visualizations, you can look to exploit this prominent space
to tell readers about a key insight or headline. However, make sure it is an
accurate reflection of the content of the visualization otherwise it will be
misleading.
• Introductions : These are really important instructive elements to explain t
he project's background and context, describing the background motivation
and what your intentions are in terms of how it should be used.
• User guides : While intuitive accessibility is stated as an overall goal, many
projects often warrant further explanation, particularly with interactive
pieces and those that have inherently complex subjects or frameworks.
In this next project, titled Political Moneyball and created by the Wall Street
Journal, we see a demonstration of exceptional care for the audience's
understanding of how to optimize this visualization's use. Not only does it
include thorough written annotation and labeling to help users understand
all the features of this incredibly immersive tool, but there is also a video
tutorial to offer that extra degree of support. The designers of this piece
astutely recognize the potential depth and interpretive complexity of the
subject matter and I imagine also want to do justice to their efforts to bring
this deep subject to fruition.
