The graph represents a network of 2,121 Twitter users whose recent tweets contained "airquality", or who were replied to or mentioned in those tweets, taken from a data set limited to a maximum of 18,000 tweets. The network was obtained from Twitter on Wednesday, 20 January 2021 at 15:32 UTC.
The tweets in the network were tweeted over the 7-day, 20-hour, 8-minute period from Tuesday, 12 January 2021 at 19:06 UTC to Wednesday, 20 January 2021 at 15:14 UTC.
Additional tweets that were mentioned in this data set were also collected from prior time periods. These tweets may expand the complete time period of the data.
There is an edge for each "replies-to" relationship in a tweet, an edge for each "mentions" relationship in a tweet, and a self-loop edge for each tweet that is not a "replies-to" or "mentions".
The graph is directed.
The graph's vertices were grouped by cluster using the Clauset-Newman-Moore cluster algorithm.
The graph was laid out using the Harel-Koren Fast Multiscale layout algorithm.
