How to draw a Technology Radar?
Here is a version in which you can load csv files into \addplots. I do not have data, so for the moment these are random plots, but if you provide data the plots can be fed with it.

I am sorry, I do not read the whole text, but I read
position each entry randomly in its segment
So, if you want a circle with some randomly shapes in it, I can help you.
Maybe you can use this as a workaround:
\documentclass[demo]{standalone}
\usepackage[dvipsnames]{xcolor}
\usepackage{tikz}
\usetikzlibrary{plotmarks}
\begin{document}
\begin{tikzpicture}[]
\foreach \s in {100,85,50,30}{
\draw[fill=lightgray!\s, draw=white] circle[radius=3*\s/100];
}
% CoSy
\draw[white, thick] (-3,0) -- (3,0);
\draw[white, thick] (0,-3) -- (0,3);
% I
\foreach \No in {0,...,33}{
\pgfmathsetmacro{\RandAngle}{random(0,900)/10}
\pgfmathsetmacro{\RandRadius}{random(0,3000)/1000}
\fill[blue] (\RandAngle:\RandRadius) circle (2pt);
}
% II
\foreach \No in {0,...,55}{
\pgfmathsetmacro{\RandAngle}{random(900,1800)/10}
\pgfmathsetmacro{\RandRadius}{random(0,3000)/1000}
\draw[green!70!black] plot[mark=triangle*,mark size=2.75pt, mark options={fill=green}] coordinates{(\RandAngle:\RandRadius)};
}
% III
\foreach \No in {0,...,55}{
\pgfmathsetmacro{\RandAngle}{random(1800,2700)/10}
\pgfmathsetmacro{\RandRadius}{random(0,3000)/1000}
\draw[orange!85!black] plot[mark=triangle*,mark size=2.75pt, mark options={fill=orange!50!yellow}] coordinates{(\RandAngle:\RandRadius)};
}
\end{tikzpicture}
\end{document}
I wanted to list my test-file such that everybody can profit from my recherche. This contains different approaches from the above and other answers (see this and that) to achieve the various blip-forms.
