## 4 Discussion  
In this study, we proposed a model for the measurement of the value of infographics, and validated the IGV short scale. We conceived a list of value items for infographics, and explored their relevance for users with an online questionnaire aimed at assessing the overall value of infographics as information and communication tools. The concept of infographics value in use or value in practice regards both implicit and explicit interaction parts; in a way, value is an effect of implicit quality and a consequences of explicitly querying infographics for information. Implicit quality is related to the extent and cognitive ease with which users can perceive and interpret information by exploiting infographics to achieve some relevant goal; explicit interaction is related to the long-term gain in value related to the decision-making based on valuable infographics. Value in use is thus the result of many implicit and explicit factors and sometimes the effect of unpredictable use and unanticipated aims.  
The five value dimensions of Usefulness, Clarity, Beauty, Informativity, and Intuitiveness proposed to the users were statistically significant in defining the overall value in infographic use. The validation

of the model depicted in Table 5 shows that all were significant with \(p\)-values \(<\) 0.001. The same table shows that all value items contributed in an equal way to the overall perceived value for the infographics, with the slight dominance of the dimensions of Usefulness, Clarity, and Beauty. Furthermore, Table 1 shows how the increase in the score of each value item doubled the probability that the infographic value would be in the upper half of positive scores, i.e., from 4 to 6.  
Our initial claim can be considered as fully plausible and partially validated by this study, and hence worth further investigation. In summary, the more an infographic is perceived as able to satisfy concrete and situated information needs in a daily context and practices, the more it is perceived as valuable. These results may suggest that, on the one hand, data have value if they are made accessible and comprehensible; on the other hand, their value lies in the comprehension itself, in the acquisition of information, facts, notions, procedures, and in the resulting knowledgeable actions. These actions (e.g., being informed, making a decision, or choosing among alternatives), in turn, produce some positive effects.  
Our final claim calls for strong generalizability of this user study, which could provide a proof of concept of value in use, of its feasibility through design, and of its utility in the evaluation of infographics.  
Further studies should attempt to understand how to obtain resources of adequate value, and hence perceivable as useful, clear, beautiful, intuitive, and informative; in this regard, a combination of many implicit factors includes immunediacy of communication, rapid exploitation, and appropriation of the information content, and aesthetic pleasure. These factors were all relevant in this experiment, as shown by the yielded results. Another aspect that should raise further questions is related to the lack of difference between respondent strata. For example, the current survey did not result in any statistically significant divergence for either gender or age.
