Hi Ruaridh, The visualization will be extremely helpful to understand what's going on. The SDR viewer is very intuitive. Are you planning also to add topology? It can be challenging to visualize the evolution of 2D SDR over time.
In addition to the spatial pooler output. It will also be useful to figure out how to visualize the synaptic connectivity pattern between cells in the temporal pooler during sequence learning. This can be challenging if you have multiple cells per column. Also, matplotlib seems to be a good library for scientific visualizations.
