For now the spatialization could be too long, maybe first check the parameters used here to improve it : https://github.com/medialab/ipysigma#quick-start

If the user does not have any graphic card on his laptop, spatialize the graph on the backend, we have some spatialization alogrithm already for layout (test with ACP, I could add another one) in src/Gargantext/Core/Viz/Graph/Tools.hs
