1. A non-transitory computer readable medium comprising program code executable by a processor for causing the processor to: receive a first plurality of values for a first layer of nodes in a neural network, a second plurality of values for a second layer of nodes in the neural network, a third plurality of values for connections between the first layer of nodes and the second layer of nodes, a fourth plurality of values for a third layer of nodes in the neural network, and a fifth plurality of values for additional connections between the second layer of nodes and the third layer of nodes; and cause a display device to output: a first quilt graph comprising: (i) a first plurality of symbols representing the first layer of nodes along a first axis, the first plurality of symbols having visual characteristics representative of the first plurality of values, (ii) a second plurality of symbols representing the second layer of nodes along a second axis that is perpendicular to the first axis, the second plurality of symbols having visual characteristics representative of the second plurality of values, and (iii) a first matrix of blocks between the first axis and the second axis, each block in the first matrix representing a respective connection between a respective node in the first layer of nodes and another respective node in the second layer of nodes and having visual characteristics indicating a value in the third plurality of values for the respective connection; a node-link diagram that visually represents the first plurality of values and the second plurality of values; and a second quilt graph adjacent to the first quilt graph, the second quilt graph comprising: (i) a third plurality of symbols representing the third layer of nodes along the first axis, the third plurality of symbols having visual characteristics representative of the fourth plurality of values, (ii) the second plurality of symbols representing the second layer of nodes along the second axis, the second plurality of symbols having the visual characteristics representative of the second plurality of values, and (iii) a second matrix of blocks between the first axis and the second axis representing the additional connections between the second layer of nodes and the third layer of nodes, the second matrix of blocks having visual characteristics representative of the fifth plurality of values.
