<h4>Exercise 2.4</h4>
<p>Answer the following questions for each of the following collections
of data graphics.</p>

<p>Briefly (one paragraph) critique the designer’s choices. Would you
have made different choices? Why or why not.</p>
<blockquote>
<p>Note: Each link contains a collection of many data graphics, and we
don’t expect (or want) you to write a dissertation on each individual
graphic. But each collection shares some common stylistic elements. You
should comment on a few things that you notice about the design of the
collection.</p>

<div id="exercise-2.5" class="section level4">
<h4>Exercise 2.5</h4>
<p>Consider one of the more complicated data graphics listed below.</p>
<ol style="list-style-type: lower-alpha">
<li>What story does the data graphic tell? What is the main message that
you take away from it?</li>
<li>Can the data graphic be described in terms of the taxonomy presented
in this chapter? If so, list the visual cues, coordinate system, and
scales(s) as you did in Problem 2(a). If not, describe the feature of
this data graphic that lies outside of that taxonomy.</li>
<li>Critique and/or praise the visualization choices made by the
designer. Do they work? Are they misleading? Thought-provoking?
Brilliant? Are there things that you would have done differently?
Justify your response.</li>
