使用d3 写了一个函数init(matrix,path)

 var Matrix = [[0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0],
            [-2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2],
            [0, 2, 0, 0, 0, -1, 0, 0, 0, 2, 0, 0, 0, -1, 0, 0, 0, 2, 0],
            [0, 2, 0, 0, 0, 0, 0, 0, 0, 2, 0, 0, 0, 0, 0, 0, 0, 2, 0],
            [0, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 0],
            [0, 2, 0, 0, 0, 0, 0, 0, 0, 2, 0, 0, 0, 0, 0, 0, 0, 2, 0],
            [0, 2, 0, 0, 0, -1, 0, 0, 0, 2, 0, 0, 0, -1, 0, 0, 0, 2, 0],
            [-2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2],
            [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0]];
			
			 var pathlist = [
			 [1,0],[1,1],[1,3]

            ];
