¿Cómo puedo hacer una línea de tiempo estándar?

Estoy buscando hacer una línea de tiempo estándar, nada sofisticado, como la siguiente (aunque no tiene que ser así) usando cualquier biblioteca. ¿Cómo puedo lograr esto de la mejor manera?

Una línea de tiempo estándar

Respuesta1

Aquí hay una posibilidad usandoTikZ:

Actualizar:

Hice algunas mejoras adicionales al código original (las versiones anteriores se pueden ver en el historial de edición de esta respuesta):

\documentclass{article}
\usepackage[margin=3cm]{geometry}
\usepackage{ragged2e}
\usepackage{fourier}
\usepackage{tikz} 
\usetikzlibrary{chains,shapes.arrows,fit}

\definecolor{arrowcolor}{RGB}{201,216,232}% color for the arrow filling
\definecolor{circlecolor}{RGB}{79,129,189}% color for the inner circles filling
\colorlet{textcolor}{white}% color for the text inside the circles
\colorlet{bordercolor}{white}% color for the outer border of circles

\pgfdeclarelayer{background}
\pgfsetlayers{background,main}

\newcounter{task}

\newlength\taskwidth% width of the box for the task description
\newlength\taskvsep% vertical distance between the task description and arrow

\setlength\taskwidth{2.5cm}
\setlength\taskvsep{17pt}

\def\taskpos{}
\def\taskanchor{}

\newcommand\task[1]{%
  {\parbox[t]{\taskwidth}{\scriptsize\Centering#1}}}

\tikzset{
inner/.style={
  on chain,
  circle,
  inner sep=4pt,
  fill=circlecolor,
  line width=1.5pt,
  draw=bordercolor,
  text width=1.2em,
  align=center,
  text height=1.25ex,
  text depth=0ex
},
on grid
}

\newcommand\Task[2][]{%
\node[inner xsep=0pt] (c1) {\phantom{A}};
\stepcounter{task}
\ifodd\thetask\relax
  \renewcommand\taskpos{\taskvsep}\renewcommand\taskanchor{south}
\else
  \renewcommand\taskpos{-\taskvsep}\renewcommand\taskanchor{north}
\fi
\node[inner,font=\footnotesize\sffamily\color{textcolor}]    
  (c\the\numexpr\value{task}+1\relax) {#1};
\node[anchor=\taskanchor,yshift=\taskpos] 
  at (c\the\numexpr\value{task}+1\relax) {\task{#2}};
}

\newcommand\drawarrow{% the arrow is placed in the background layer 
                                                     % after the node for the tasks have been placed
\ifnum\thetask=0\relax
  \node[on chain] (c1) {}; % if no \Task command is used, the arrow will be drawn
\fi
\node[on chain] (f) {};
\begin{pgfonlayer}{background}
\node[
  inner sep=10pt,
  single arrow,
  single arrow head extend=0.8cm,
  draw=none,
  fill=arrowcolor,
  fit= (c1) (f)
] (arrow) {};
\fill[white] % the decoration at the tail of the arrow
  (arrow.before tail) -- (c1|-arrow.west) -- (arrow.after tail) -- cycle;
\end{pgfonlayer}
}

\newenvironment{timeline}[1][node distance=.75\taskwidth]
  {\par\noindent\begin{tikzpicture}[start chain,#1]}
  {\drawarrow\end{tikzpicture}\par}

\begin{document}

\begin{timeline}
\Task{Complete oral presentation\\ 27/04/2012}
\Task{Work on user interface and some modulation \\ 28/04/2012}
\Task{Work on and complete proposal to hand in \\ 29/04/2012}

\definecolor{arrowcolor}{RGB}{144,168,65}
\colorlet{circlecolor}{white}
\definecolor{bordercolor}{RGB}{168,89,65}
\colorlet{textcolor}{bordercolor}
\setlength\taskwidth{1.7cm}

\begin{timeline}
\Task[M]{Grilled cheese sandwiches on whole-wheat bread, one peach}
\Task[Tu]{Penne pasta Caprese salad}
\Task[W]{Zucchini muffins with cream cheese, grapes, and watermelon}
\Task[Th]{Peanut butter and banana sandwiches, popcorn, one peach}

Cómo funciona el código:

Dentro del timelineentorno, utilizar \Task{<description>}para cada tarea. Por ejemplo:

\begin{timeline}
\taskmark{This is the first task}
\taskmark{This is the description of the second task and it is a little long}
\taskmark{This is the description of the third task and it is short}
\taskmark{This is the description of the fourth task}
\taskmark{This is the description of the fifth task}
\taskmark{Here is the description of the sixth task}
\end{timeline}

Si no \Taskse utiliza ningún comando, sólo se dibujará la flecha. El argumento opcional para \Task, permite agregar una etiqueta a los círculos internos (si la etiqueta es demasiado larga, innerse deberá aumentar el ancho del estilo).

Con PSTricks.

\documentclass[pstricks,border=12pt]{standalone}
\usepackage{etoolbox}
\SpecialCoor
\def\Mark#1#2#3{%
    \pscircle[linewidth=2pt,linecolor=white,fillstyle=solid,fillcolor=blue!75](!2.5 #1 mul 1 add 0){.5}
    \ifstrequal{#2}{t}{%
        \rput[b](!2.5 #1 mul 1 add  1){\parbox{2cm}{\scriptsize #3}}}{%
        \rput[t](!2.5 #1 mul 1 add -1){\parbox{2cm}{\scriptsize #3}}}}

\def\Axis#1{%
    \psline[linecolor=blue!50,linewidth=1.5,arrowinset=0,arrowlength=0.5]{->}(0,0)(!2.5 #1 mul 5 add 0)
    \pspolygon*[linecolor=white](0,.75)(.75,0)(0,-.75)}

\begin{document}
\begin{pspicture}(0,-3)(10,3)
    \Axis{2}
    \Mark{0}{t}{Karl's students do not care about dashing patterns.}
    \Mark{1}{b}{Karl's students do not care about arrow tips.}
    \Mark{2}{t}{Karl's students, by the way, do not know what a transformation matrix is.}
