<p>I recently <a href="https://stats.stackexchange.com/a/31966">answered a question</a> that seemed to address the original question's issue (i.e. how to visualize some data).  Then, in the comments, there was an implied follow-on question about how the visualization was created.</p>

<p>Is this an appropriate time to create a new question (e.g. how was the visualization created?) and answer it?  Or, would the community be better served by adding onto the answer to the original question?  I'm particularly curious about cases where answering the second comment/question will be lengthy and probably off-target from the original question.</p>
