Diagramme en TikZ avec des explicatifs
Bonjour chère communauté,
Veuillez bien m'aider à réaliser ce diagramme sous tikz (urgent). En effet, j'essaie depuis trois jours mais je ne suis pas arrivé à le faire. Ci joint mon code et le diagramme que je souhaiterais avoir.
\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{arrows,shapes,positioning,shadows,trees}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[english, frenchb]{babel}
\usepackage{ucs}
\usepackage{smartdiagram}
\usepackage{pgf,pgfarrows,pgfnodes,pgfautomata,pgfheaps,pgfshade}
\usepackage{lmodern}
\tikzset{
basic/.style = {draw, text width=12em, drop shadow, font=\sffamily, rectangle},
root/.style = {basic, rounded corners=2pt, thin, align=center,
fill=cyan!30},
level 2/.style = {basic, rounded corners=6pt, thin,align=center, fill=cyan!60,
text width=8em},
level 3/.style = {basic, thin, align=left, fill=pink!60, text width=6.5em}
}
\begin{document}
\begin{tikzpicture}[
level 1/.style={sibling distance=40mm},
edge from parent/.style={->,draw},
>=latex]
% root of the the initial tree, level 1
\node[root] {Indicateur \mbox{d'insécurité} alimentaire}
% The first level, as children of the initial tree
child {node[level 2] (c1) {SCA}}
child {node[level 2] (c2) {PDA}}
child {node[level 2] (c3) {ISS}};
% The second level, relatively positioned nodes
\begin{scope}[every node/.style={level 3}]
\node [below of = c2, xshift=20pt, text width=6cm, draw](c21) {Cartographie de \mbox{l’insécurité} alimentaire};
\node [below of = c21, xshift=20pt, text width=4cm, draw](c22) {Analyse statistique bivariée};
\node [below of = c22, xshift=20pt, text width=4cm, draw](c23) {ACM suivie d'une CAH};
\node [below of = c23, xshift=20pt, text width=2cm, draw](c25) {GLOGIT2};
\end{scope}
\end{tikzpicture}
\end{document}
