现在我们已经构建了简化的函数连通性矩阵，接下来应该构建图形的表示了。

Now that the compact function connectivity matrix is built, it's time to build its graph.

在分析跟踪文件中的调用链时，会构建一个连通矩阵，用来表示哪个函数调用了其他哪些函数。

As the call chain is parsed from the trace file, a connectivity matrix is built that identifies which functions call which other functions.

为此，给出了连通区域搜索算法，定义了用于区分表格与图形的行程位置转化函数。

So a researching algorithm of connected area is given, a function of routing change position is defined for the distinguish of table and graph.
