This module crawls a network of channels connected via the "featured channels" (and via subscriptions) tab from a list of seeds. Featured channels are retrieved via channels/list#brandingSettings and subscriptions via subscriptions/list. Seeds can be channels retrieved from a search or via manual input of channel ids.
Crawl depth specifies how far from the seeds the script should go. Crawl depth 0 will get only the relations between seeds. Using many seeds and the maximum crawl depth (2) can take a very long time or the script might run out of memory. Start small.
NB: since graph analysis software can have difficulties with very large numbers, channels' viewcount is given in 100s.
