创建一个具有大量边的图

Question

我正在尝试在 Latex 中创建一个具有大量边的图形。类似于所附图像（取自 Bissyandé 等人的论文）。

我试图使用 tikzpicture 和一些边简单地绘制一个图形，但是如何从外部文件（CSV？！）导入边以及如何根据值更改边的粗细？

这是我迄今为止所做的起点：

\begin{tikzpicture}
    \begin{pgfonlayer}{nodelayer}
        \node [style=none] (0) at (-1.25, 4.5) {C};
        \node [style=none] (1) at (3.5, 4.5) {C++};
        \node [style=none] (2) at (3.5, 2.5) {HTML};
        \node [style=none] (3) at (-2.75, 2.5) {JavaScript};
        \node [style=none] (4) at (1.25, 5) {Python};
        \node [style=none] (5) at (1.25, 1.75) {CSS};
        \node [style=none] (6) at (3.75, 6) {Shell};
        \node [style=none] (7) at (-2.25, 5.75) {Objective-C};
        \node [style=none] (8) at (1.75, -0.5) {PHP};
        \node [style=none] (9) at (5, 0) {Java};
        \node [style=none] (10) at (5.25, 3.5) {Makefile};
        \node [style=none] (11) at (-1.75, 0) {Ruby};
    \end{pgfonlayer}
    \begin{pgfonlayer}{edgelayer}
        \draw (0.center) to (3.center);
        \draw (0.center) to (2.center);
        \draw (2.center) to (1.center);
        \draw (3.center) to (1.center);
        \draw (11.center) to (5.center);
        \draw (11.center) to (3.center);
        \draw (11.center) to (0.center);
        \draw (8.center) to (0.center);
        \draw (7.center) to (0.center);
        \draw (4.center) to (5.center);
        \draw (0.center) to (4.center);
        \draw (4.center) to (1.center);
        \draw (6.center) to (10.center);
        \draw (10.center) to (9.center);
        \draw (9.center) to (2.center);
        \draw (2.center) to (10.center);
        \draw (8.center) to (5.center);
        \draw (8.center) to (2.center);
    \end{pgfonlayer}
\end{tikzpicture}

谢谢！
