\section{Basic diagram}

\begin{tikzpicture}
  % Define timelines with their names, and ordinate as #2:
  \tline{A}{2};
  \tline{B}{0};
  % Actually draw the timelines (#2 is the horizontal length):
  \ttimeline{A}{5};
  \ttimeline{B}{5};
  % Provide captions for timelines:
  \tcaption{A}{A's caption};
  \tcaption{B}{B's caption};
  
  % Draw the actual content:
  % tick = vertical line accros the timeline
  \ttick{A};
  % advance time
  \tskip{A}{2};
  % This one will be drawn 2 time units after the previous, because of
  % the \tskip:
  \ttick{A};
  
  % One more with the same principle:
  \tskip{A}{1};
  \ttick{A};

  % Same as above, but on timeline B:
  \ttick{B};
  \tskip{B}{1};
  % \tbox creates a box with non-null width, and text inside:
  \tbox{B}{3}{Box on B};
