It's been a while since I started my loose series of blog posts giving insights into the basic facts and features of Gantt charts by writing about why they are still popular today.
I'm quite sure that to some the actual nature and structure of these charts has become a bit vague over times, what with further developments and extending of application fields. So I considered clarifying the graphical ingredients of a Gantt chart in the first place.
Possibly, you'll be surprised that the text is rather short. But first, as I'd like to clear the above mentioned vagueness, I'm going to keep my explanation as detailed as necessary and as concise as possible. Second, a structure as simple - yet effective - doesn't need much words to be explained. And third, when it comes to a visualization technique like a Gantt diagram, I rather prefer to work with images than with words.
