I have generated the following
using Tikz. I then would like to wrap it with text as in (the red boxes) :

Is there a way to achieve this? knowing that the flowchart (generated separately) is included in my main as a pdf
Update: After the first comment, I think it is better if i include the flowchart code into the main. Here is a MWE:
\documentclass{article}
\usepackage{ulem,tikz,amsmath, amssymb,bm,color}
\usepackage[english]{babel}
\usepackage{lipsum}
\usepackage[margin=0cm,nohead]{geometry}
\usetikzlibrary{shapes,arrows}
\usepackage{pgfplots}
\usepackage{wrapfig}
% needed for BB
\usetikzlibrary{calc}
\usetikzlibrary{shapes,arrows}
\tikzstyle{line} = [draw, -latex']
\begin{document}
\lipsum[5]
\begin{wrapfigure}{r}{0.5\textwidth}
\begin{center}
\begin{tikzpicture}[node distance =1.5cm,auto]
% Place nodes
\node [draw,rounded corners] (node1) {a};
\node [draw,rounded corners, below of=node1] (node2) {b};
\node [draw,rounded corners, below of=node2] (node3) {c};
\node [ below of=node3] (Inter1){};
\node [draw,rounded corners, right of=Inter1,node distance =2.5cm] (node4) {d};
\node [draw,rounded corners, right of=node4,node distance =3.5cm] (node5) {d};
\node [draw,rounded corners, left of=Inter1,node distance =2.5cm] (node6) {d};
\node [draw,rounded corners, left of=node6,node distance =3.5cm] (node7) {d};
\node [ below of=node7] (Inter2){};
\node [draw,rounded corners, right of=Inter2] (node8) {d};
\node [draw,rounded corners, left of=Inter2] (node9) {d};
\node [ below of=node8] (Inter3){};
% % Draw edges
\path[line] (node1) -- (node2);
\path [line] (node2) -- (node3);
\path [line] (node3) --++(-90:8mm)-| (node4.north);

\path [line] (node7)--++(-90:8mm)-| (node8.north);
\path [line] (node7) --++(-90:8mm)-| (node9.north);
\end{tikzpicture}\caption{Example graphic made with tikz.}

\end{wrapfigure}

\parshapecommand to shape the right edge of the paragraph. The figure doesn't need to be transparent, but instead to have "zero width" at the eyes of tex, so that it is "overimposed" on the paragraph, but it will have appropiate "holes" thanks to\parshape.
