Chartjunk
open-in-new
<h2 id="etymology">Etymology</h2> <p>The term chartjunk was first coined by Edward Tufte in 1983.<a class="footnote-ref" id="fnref:7" href="#fn:7"><sup>7</sup></a> The book was developed based on ideas and materials developed for a Princeton statistics course that Tufte co-taught with <a href="/facts/John_Tukey/2a5FbPWb">John Tukey</a>. As a self-published book, <i>The Visual Display of Quantitative Information,</i> Tufte claims that good design is founded in <a href="/facts/Minimalism/BMNlancL">minimalist</a> design principles. Specifically, he states that "graphics reveal data"<a class="footnote-ref" id="fnref:8" href="#fn:8"><sup>8</sup></a> if they are designed with "graphical integrity."<a class="footnote-ref" id="fnref:9" href="#fn:9"><sup>9</sup></a> Tufte, through minimalist design principles, was committed to an objective and neutral values of science. Other researchers have argued that minimalism is not objective and is full of its own rhetoric and potential to bias.<a class="footnote-ref" id="fnref:10" href="#fn:10"><sup>10</sup></a><a class="footnote-ref" id="fnref:11" href="#fn:11"><sup>11</sup></a> </p><p>Tufte, in coining the term chartjunk, also made direct comments about a well-known designer at that time, <a href="/facts/Nigel_Holmes/wHjwHxQF">Nigel Holmes</a>.<a class="footnote-ref" id="fnref:12" href="#fn:12"><sup>12</sup></a> </p> <blockquote><p>Nearly all those who produce graphics for mass publication are trained exclusively in the fine arts and have had little experience with the analysis of data. Such experiences are essential for achieving precision and grace in the presence of statistics ... Those who get ahead are those who beautified data, never mind statistical integrity.</p></blockquote> <p>Further, in his second published book, <i>Envisioning Information</i>,<a class="footnote-ref" id="fnref:13" href="#fn:13"><sup>13</sup></a> Tufte critiques Holmes' D<i>iamonds</i> chart:<a class="footnote-ref" id="fnref:14" href="#fn:14"><sup>14</sup></a> </p> <blockquote><p>Consider this unsavory exhibit at right – chockablock with cliché and stereotype, coarse humor, and a content-empty third dimension ... Credibility vanishes in clouds of chartjunk; who would trust a chart that looks like a video game?</p></blockquote> <p>In a 1992 <a href="/facts/The_New_York_Times/T9marWVX">New York Times</a> article, the reporter captures Holmes' response to Tufte's criticism:<a class="footnote-ref" id="fnref:15" href="#fn:15"><sup>15</sup></a> </p> <blockquote><p>Time's Nigel Holmes, creator of the diamonds graph, was understandably irked when Tufte criticized it. Holmes admits his work has sometimes been exaggerated, but feels that Tufte, in his insistence on absolute mathematical fidelity, remains trapped in "the world of academia" and insensitive to "the world of commerce", with its need to grab an audience</p></blockquote> <p>This debate between Tufte and Holmes is emblematic of the tension between statistical and designerly approaches to visualization design.<a class="footnote-ref" id="fnref:16" href="#fn:16"><sup>16</sup></a><a class="footnote-ref" id="fnref:17" href="#fn:17"><sup>17</sup></a><a class="footnote-ref" id="fnref:18" href="#fn:18"><sup>18</sup></a> </p> <h2 id="debate-over-meaning">Debate over meaning</h2> <p>The term chartjunk is an umbrella term that can be used to describe a variety of visual devices and has been referenced by different terms across research. </p> Chartjunk Alternative Terms<table><tbody><tr><th>Term</th><th>Citation</th></tr><tr><td>embellishment</td><td><a class="footnote-ref" id="fnref:19" href="#fn:19"><sup>19</sup></a><a class="footnote-ref" id="fnref:20" href="#fn:20"><sup>20</sup></a></td></tr><tr><td>excessive annotation</td><td><a class="footnote-ref" id="fnref:21" href="#fn:21"><sup>21</sup></a></td></tr><tr><td>decoration</td><td><a class="footnote-ref" id="fnref:22" href="#fn:22"><sup>22</sup></a></td></tr><tr><td>extraneous elements</td><td><a class="footnote-ref" id="fnref:23" href="#fn:23"><sup>23</sup></a></td></tr><tr><td>unnecessary ornamentation</td><td><a class="footnote-ref" id="fnref:24" href="#fn:24"><sup>24</sup></a></td></tr></tbody></table> <p>Stephen Few, a data visualization practitioner and consultant at Perceptual Edge, stated that Tufte's original definition of chartjunk was "too loose" and that "by defining chartjunk too broadly, Tufte to some degree invited the heated controversy that has raged ever since."<a class="footnote-ref" id="fnref:25" href="#fn:25"><sup>25</sup></a> </p><p>Robert Kosara, also a data visualization practitioner, researcher, and author of the blog EagerEyes, noted that not all chartjunk are the same, some are harmful (e.g. a busy background), others harmless (e.g. nice borders or pictures), and some even helpful (e.g. annotations).<a class="footnote-ref" id="fnref:26" href="#fn:26"><sup>26</sup></a> </p><p>In a recent study by Parsons and Shukla,<a class="footnote-ref" id="fnref:27" href="#fn:27"><sup>27</sup></a> they interviewed data visualization designers and found that there is both a "corrective movement" in the design community to move away from minimalist design principles, but also, that designers had different definitions for what constitutes chartjunk. The authors felt that "better definitions are needed so that everyone has a shared understanding [about chartjunk]." </p> <h2 id="chartjunk-in-research">Chartjunk in research</h2> <p>The <a href="/facts/Information_visualization/DSHteV85">information visualization</a> research community has researched the effects of chartjunk on how viewers interpret visualizations.
