Node sizes represent the average CCV (Concurrent Viewers) for the past month of the streamer.

Arrows indicate shared chatters:

An arrow from a streamer (source) to another streamer (target) means that a percentage of the source's chatters also actively participate in the target's chat.
To count as a chatter, a user must have sent at least five messages in the stream.
For an arrow to appear, the percentage of shared chatters (relative to the source's CCV) must exceed a threshold, typically 10% or 12%.
The thickness of the arrow represents the percentage of shared chatters: thicker lines mean higher percentages.

Directional relationships:

Often, there will be a one-way connection (e.g., source to target) without a reciprocal arrow (target to source).
This asymmetry arises because smaller streamers can more easily share a significant percentage of their chatters with larger streamers than vice versa. For example, 10% of a 100 CCV stream is a much smaller absolute number than 10% of a 5000 CCV stream.

For whatever reason, catbox puts these on a white background but the images are transparent.

Community groupings (node colors) were assigned using the Louvain method

Community Graph 1 - https://files.catbox.moe/vm79jc.png
Threshold: 10 percent or greater shared chatters, 5 messages or more

Community Graph 2 - https://files.catbox.moe/elvycu.png
Threshold: 12 percent shared chatters, 5 messages or more
