Network visualization slowing page down #229
Description
With currently 8104 nodes and 7161 open channels on the network of the TTT token http://goerli.explorer.raiden.network is pretty slow again.
Transforming the visualization to a canvas brought us some performance gains, but it seems like the calculation of the animation is still a problem with a high amount of nodes / channels. This is because for every step of the animation d3.js calculates the position of the nodes and channels. See this for an explanation.
I think we should try to move to a static (not animated) visualization of the network and calculate the position of nodes before showing it.
