Hi Ioannis,
Thank you for your kind words. It is always nice to get some positive feedback. 
Indeed, cranly seems very relevant to my app. Thank you for pointing me in this direction. I think the networks are a good way to browse the landscape of packages and to discover other popular libraries. I am thinking about adding more features to the network graph, e.g. colorising nodes by publication time to better spot new packages that are interesting for a particular use case scenario. I will check out cranly for additional inspiration as well.
Thanks,
Stefan
