Comment (by asn):

 Replying to [ticket:13638 hellais]:
 > Currently we use the bridge fingerprint as a unique key in the bridge
 reachability timeline graph. This leads to different bridges categorised
 as a certain pluggable transport type, since it's possible for a bridge
 with the same fingerprint to run on multiple pluggable transports.

 In the final visualization, it would be good if the bridge identifier was
 just `H(bridge_fingerprint)`, so that people can search for specific
 bridges without calculating
 `H(bridge_fingerprint+pluggable_transport_type)`.

 Not sure if this is still possible with the key being
 `H(bridge_fingerprint+pluggable_transport_type)`.
