How to use to_graphviz() in MXNet to view a network?

I’m starting with MXNet and I would like to see the visualize the network I make. If I’m using IJulia, I can just call
mx.to_graphviz(my_net) to visualize it on my jupyter notebook. But if I’m in REPl, how to do this? Like, how to plot the figure to a PyPlot like interface??
