我有一张 tikz 图片。这是一张图表。我创建了一个演示文稿，它在演示文稿中显示正确。因此，代码是正确的。但现在我正在制作学位作品，我有
\documentclass{report}
但是图片没有显示出来，代码如下：
\begin{tikzpicture}
\tikzset{VertexStyleOrange/.style = {
shape = circle,
ball color = orange,
inner sep = 1pt,
outer sep = 0pt,
minimum size = 1 pt}}
\tikzset{VertexStyleBlue/.style = {
shape = circle,
ball color = blue,
inner sep = 1pt,
outer sep = 0pt,
minimum size = 1 pt}}
\tikzset{EdgeStyleBlue/.style = {thick,
double = blue,
double distance = 1pt}}
\tikzset{EdgeStyle/.style = {thick,
double = orange,
double distance = 1pt}}
\node at ( -3.5,3)[VertexStyleOrange](0) {0};
\node at ( -5,1)[VertexStyleBlue](1) {1};
\node at ( -2,1)[VertexStyleBlue](2) {2};
\node at ( -2,-1)[VertexStyleBlue](3) {3};
\node at ( -5,-1)[VertexStyleBlue](4) {4};
\node at ( -3.5,-3)[VertexStyleOrange](5) {5};
\node at ( 3.5,3)[VertexStyleOrange](6) {0};
\node at ( 5,1)[VertexStyleBlue](7) {1};
\node at ( 2,1)[VertexStyleBlue](8) {2};
\node at ( 2,-1)[VertexStyleBlue](9) {3};
\node at ( 5,-1)[VertexStyleBlue](10) {4};
\node at ( 3.5,-3)[VertexStyleOrange](11) {5};
\draw[EdgeStyle](1) to node{}(0);
\draw[EdgeStyle](2) to node{}(0);
\draw[EdgeStyleBlue](1) to node{}(2);
\draw[EdgeStyleBlue](2) to node{}(3);
\draw[EdgeStyleBlue](3) to node{}(4);
\draw[EdgeStyleBlue](4) to node{}(1);
\draw[EdgeStyleBlue](1) to node{}(3);
\draw[EdgeStyleBlue](4) to node{}(2);
\draw[EdgeStyle](5) to node{}(3);
\draw[EdgeStyle](4) to node{}(5);
\draw[EdgeStyle](11) to node{}(7);
\draw[EdgeStyle](11) to node{}(8);
\draw[EdgeStyle](6) to node{}(10);
\draw[EdgeStyle](6) to node{}(9);
\end{tikzpicture}
但我看到的不是这个，而是一个小黑点。我把它贴在文件的所有地方，但结果都一样——一个小小的黑色污点。这是什么原因呢？

即使删除 \begin{center} 后图片也不会显示

运行完美，但你可以稍微修改一下代码

\usepackage{tikz}
\usetikzlibrary{%
arrows,
calc
}
