Hi, I just want to know that is it possible to plot 2D projections of root systems (e.g. D6, E6, E7, E8 etc.) using sage? I am in search of proper software that can help me implement these systems. My initial work will concentrate on calculating the voronoi cells of different lattices and plotting their projections. So please anyone can tell me that sage will be a right option or I should consider Maple or Magma as I have seen that people have already done this work using these software ( http://www.math.lsa.umich.edu/~jrs/coxplane.html<https://hknprd0111.outlook.com/owa/redir.aspx?C=TXA2zSovyE-3iY6bk_B3KL8Q84-P188Iz45slt0WQr9gi_AVEngcUmzP2IERT1xRXEeSVf5BIjw.&URL=http%3a%2f%2fwww.math.lsa.umich.edu%2f%7ejrs%2fcoxplane.html> ).
