% \begin{abstract}
% This package provides a way to easily draw diagrams in documents and presentations from a list of items thanks to Ti\textit{k}Z.
% The idea cames out from \href{http://tex.stackexchange.com/questions/78310/powerpoints-smart-art-for-tikz}{this question} on \href{http://tex.stackexchange.com}{TeX.StackExchange}.
%
% \end{abstract}

% \section{Introduction and requirements}
% The aim of the package is to provide a way to draw diagrams starting from a list of items colored automatically. The diagrams created could be used in a simple document or in a presentation: in the latter case, while using the Beamer class, the user could decide if diagrams should be overlay-awared or not.
% 
% Automatically, the \textsf{smartdiagram} package loads:
% \begin{itemize}
% \item Ti\textit{k}Z;
% \item \textsf{etoolbox};
% \item \textsf{xparse}.
% \end{itemize}
% Moreover, the package loads the following Ti\textit{k}Z libraries:
% \begin{itemize}
% \item \library{backgrounds};
% \item \library{calc};
% \item \library{fadings};
% \item \library{shadows};
% \item \library{shapes.arrows}.
% \end{itemize}
% and it sets a new layer called \verb|smart diagram arrow back|.
% 
% The package could be loaded by means of \cs{usepackage}\texttt{\{smartdiagram\}}.
% 
% \section{Basic Usage}
% \DescribeMacro{\smartdiagram} The basic command is \cs{smartdiagram}\mqbarg{type of diagram}\mbrarg{list of items}. The \mbrarg{list of items} should be comma-delimited: to insert, for example, a comma as part of the item label use \verb|\smartdiagram[..]{elem1,{elem2,text},elem3}|.
%
% The possible diagrams that could be created are:
% \begin{itemize}
% \item \diagram{circular diagram}: the items in the list are diplayed around a circle;
% \item \diagram{flow diagram}: the items in the list are diplayed as a flow chart;
% \item \diagram{descriptive diagram}: a diagram in which are displayed concepts and their description;
% \item \diagram{priority descriptive diagram}: a diagram in which the items are deployted based on their relevance;
% \item \diagram{bubble diagram}: each item is a bubble deployted around a bubble center, which is the first element in the list;
% \item \diagram{constellation diagram}: each item is a circle connected to the center, the first element in the list again;
% \item \diagram{connected constellation diagram}: each item is a circle and, a part from the first element in the list, the other ones are connected toghether.
% \end{itemize}
% 
% For example:
% \begin{verbatim}
% \begin{center}
% \smartdiagram[circular diagram]{Set up,Run,Analyse,Modify~/ Add}
% \end{center}
% \end{verbatim}
% produces:
% \begin{center}
% \smartdiagram[circular diagram]{Set up,Run,Analyse,Modify~/ Add}
% \end{center}
%
% All diagrams could be customized in various ways, from the selection of the background colors to the font size, from the size of the items to the shape of the border. The keys necessary for this task will be analysed in detail in section \ref{sec:options}.
%
% For what concern the \diagram{bubble diagram}, the \diagram{constellation diagram} and the \diagram{connected constellation diagram}, they are a bit different from the rest of the diagrams, in the sense that the first item in the \mbrarg{list of items} is particular: called \emph{bubble center} and \emph{planet}, respectively, its aspect is different and it could be customized with dedicated keys.
%
% \DescribeMacro{\smartdiagramanimated} Inside presentations, the user could select if the diagram should be displayed in a \emph{persistent} way, or with an animation. The \emph{persistent} way is achieved by exploiting, again, \cs{smartdiagram}, while to have the diagram \emph{overlay-aware} the command is \cs{smartdiagramanimated}\mqbarg{type of diagram}\marg{list of items}. 

% For diagrams like the \diagram{circular diagram} and the \diagram{flow diagram} the animation runs as follows: at the beginning the first item of the list is displayed, then each time appears an arrow connecting the previous element with the new one; at the end it is displayed the arrow connecting the last element with the first one. Considering instead the \diagram{descriptive diagram}, per couple description title-description, first it is shown the description title and subsequently the description. In the \diagram{priority descriptive diagram}, very simply, the list of items is deployted starting from the bottom, that is the less relevant item, to the top to progressively show much relevant items.
% Finally, for the \diagram{bubble diagram}, the \diagram{constellation diagram} and the \diagram{connected constellation diagram}, at first it is always shown the \emph{bubble center} and \emph{planet}, respectively and later all the items subsequently.
% 
% 
% \section{The options}
% \label{sec:options}
% \subsection{Setting the options}
% \DescribeMacro{\smartdiagramset} The options should be introduced similarly to what happens with \cs{tikzset} in Ti\textit{k}Z: \cs{smartdiagramset}\mbrarg{list of options}. Examples in which some options are used are shown in section \ref{sec:gallery}.
% \subsection{Available options}
% Here follows the list of general available options.
% \subsubsection{General options}
% \begin{itemize}
% \item \packoption{module minimum width}{2cm}: this option sets the minimum width of the module;
%
% \item \packoption{module minimum height}{1cm}: this option sets the minimum height of the module;
%
% \item \packoption{module y sep}{1.65}: this option sets a vertical distance factor among the modules in a \verb|flow diagram|;
%
% \item \packoption{module shape}{rectangle,rounded corners}: this option should be used to change the shape of the module, but the user should load manually the proper Ti\textit{k}Z library; for example, to user an \verb|ellipse|, load \library{shapes.geometric} in the preamble;
%
% \item \packoption{text width}{1.75cm}: this option sets the text width inside the module;
%
% \item \packoption{font}{\textbackslash small}: this option sets the module font;
%
% \item \packoption{border color}{gray}: this option sets the border color of the module;

% \item \packoption{circular distance}{2.75cm}: this option sets the radius of cirle around which the modules in a \verb|circular diagram|;
%
% \item \packoption{arrow line width}{0.1cm}: this option sets the width of the connection arrows within two modules;
%
% \item \packoption{set color list}{none}: this option allows the user to define the list of colors usable in the diagram;
%
% \item \packoption{use predefined color list}{none}: this option allows the user to reuse the pre-defined colors whenever in a previous diagram they have been changed;
%
% \item \packoption{insert decoration}{none}: this option allows to decorate the border of the module; the user should declare properly a decoration style and load manually the libraries required, e.g. \library{decorations.pathmorphing}; some more hints are given in section \ref{sec:recommendations};

% \end{center}
%
% \section{Recommendations and known issues}
% \label{sec:recommendations}
% \subsection{Something about colors}
% As seen in the section \ref{sec:options}, the colors could be customized by means of the key \smkey{set color list}. By default there are 10 predefined colors; in order:  \colsmartbox{red!40}, \colsmartbox{cyan!40}, \colsmartbox{blue!40}, \colsmartbox{green!40}, \colsmartbox{orange!40}, \colsmartbox{yellow!40}, \colsmartbox{magenta!40}, \colsmartbox{brown!40}, \colsmartbox{violet!40} and \colsmartbox{teal!40}. This implies that, by default, it is not possible to have list longer than 10 items. This, of course, could be avoided by declaring its own proper list with, say, 20 colors and therefore develop diagrams with more than 10 items. In any case, it is always possible to reset custom color lists by means of:
% \begin{verbatim}
% \smartdiagramset{use predefined color list}
% \end{verbatim}
% 
% \subsection{Circular, bubble and constellation diagrams}
% For these type of diagrams, the number of items is relevant: too many items lead to overlapping satellites and bubbles besides any attempt to resize things by means of keys that reduce the radius. 
% 
% Notice also that imposing a too short distance from the planet to satellites is bad and leads to something like:
% \begin{verbatim}
% \begin{center}
% \smartdiagramset{planet color=orange!60, distance planet-satellite=1cm}
% \smartdiagram[connected constellation diagram]
%  {Build a program,Set up,Run,Analyze,Modify~/\\ Add,Check}
% \end{center}
% \end{verbatim}
% \begin{center}
% \scalebox{0.8}{
% \smartdiagramset{planet color=orange!60, distance planet-satellite=1cm}
% \smartdiagram[connected constellation diagram]{Build a program,Set up,Run,Analyze,Modify~/\\ Add}
% }
% \end{center}
% 
% \subsection{Descriptive diagrams}
% When the user has to build a \diagram{descriptive diagram}, simple or animated, the following rules have to be respected:
% \begin{itemize}
% \item each description title and description should be separated by a comma;
% \item to use a comma inside a description, enclose by \{ \} the description;
% \item use a comma after the last couple description title-description. 
% \end{itemize}
% A working example:
% \begin{verbatim}
% \smartdiagram[descriptive diagram]{
% {Set up,The set up operation consist of..},
% {Run, {After having set up the program, you must run..}},
% {Analyze, You must check what did with analytical tools like..},
% }
% \end{verbatim}
% A non-working example:
% \begin{verbatim}
% \smartdiagram[descriptive diagram]{
% {Set up,The set up operation consist of..},
% {Run, {After having set up the program, you must run..}},
% {Analyze, You must check what did with analytical tools like..}
% }
% \end{verbatim}
% The \emph{mandatory} final comma is missing thus, as result, the last couple description title-description will be entirely treated as a description title.
%
% Another suggestion regarding descriptive diagrams is about the description title: it should be short in order to avoid the size of the circle explode. To kept it under controll, the keys \smkey{description title width}, \smkey{description title text width} and \smkey{description title font} are of help. 
%
% \subsection{Decorations}
% To decorate the border of modules, it is kindly recommended to first declare the decoration choosen by means of an apposite style and then apply the style. The procedure, in code, should be as follows:
% \begin{verbatim}
% \tikzset{my wonderful decoration/.style={decorate,decoration=bent}}
% \smartdiagramset{insert decoration=my wonderful decoration,...}
% \end{verbatim}
% where the dots represent the other options.
%
% The insertion of decorations inside a \diagram{descriptive diagram} are problematic: only \verb|random steps|, \verb|bent| and \verb|coil| do not raise errors. Other decorations, like \verb|coil|, raise as error: 
% \begin{verbatim}
% ! Dimension too large.
% \end{verbatim} but, after all, the decoration is deployted anyway.
% 
% In case the user wants to decorate a border with a decoration that involves random numbers, such as \verb|random steps| or other custom-built decorations, it is preferable to set a seed for the animated diagram, to avoid that at each step the border of the same module changes. An example:
% \begin{verbatim}
% \begin{frame}
% \begin{center}
% \pgfmathsetseed{12354}
% \tikzset{my decoration/.style={decorate,decoration=random steps}}
% \smartdiagramset{insert decoration=my decoration}
% \smartdiagramanimated[descriptive diagram]{
% {Set up,The set up operation consist of..},
% {Run, {After having set up the program, you must run..}},
% {Analyze, You must check what did with analytical tools like..},
% {Modify, {After the analysis, you can still modify or add..}},
% }
% \end{center}
% \end{frame}
% \end{verbatim}
% 
% \subsection{Priority descriptive diagrams}
% The vertical arrow is drawn in background with a fading effect: it may occurr that under some pdf editor this effect is not shown (this happened to me with evince, but it perfectly worked with okular).
% 
% For what concern these diagrams there is a bug in displaying the tick line when the \smkey{priority arrow head extend} is set with a bigger size than the default; a minimal-non-working example:
% \begin{verbatim}
% \begin{center}
% \smartdiagramset{priority arrow width=2cm,priority arrow height advance=2.25cm,
%  priority arrow head extend=0.3cm}
% \smartdiagram[priority descriptive diagram]{PGF,Ti\textit{k}Z,Smartdiagram}
% \end{center}
% \end{verbatim}
% \begin{center}
% \smartdiagramset{use predefined color list}
% \smartdiagramset{priority arrow width=2cm,priority arrow height advance=2.25cm,
%  priority arrow head extend=0.25cm}
% \scalebox{0.8}{
% \smartdiagram[priority descriptive diagram]{PGF,Ti\textit{k}Z,Smartdiagram}
% }
