We present Fireflies, an exploration of bio-inspired visualization using animal swarming behaviours and plant phyllotaxis. We applied Fireflies to a Canadian attitudinal survey on HIV/AIDS. Information about the survey participants is encoded within different visual elements of fireflies; most importantly, the motion of the fireflies depicts comfort levels concerning HIV/AIDS. The bio-inspired ...
