<p>Actually, there are two tags for questions that are related (to some extent) to data visualization: <a href="https://stats.stackexchange.com/questions/tagged/data-visualization">data-visualization</a> (44) and <a href="https://stats.stackexchange.com/questions/tagged/graphical-techniques">graphical-techniques</a> (37). What's the difference, if any?</p>

<p>Maybe there are some subtle differences between them that I cannot grasp actually. From what has been posted so far, my understanding is as follows: <em>data visualization</em> has to do with "how to display data" (broadly speaking) and "what can I use to display my data" (more of a software issue), whereas <em>graphical techniques</em> is perhaps more related to "how may I provide a visual explanation of my data structure".</p>

<p>I am asking that question because I often feel confused when trying to retag some questions.</p>

<p>Any ideas or thoughts on that?</p>
