The graph represents a network of 487 Twitter users whose tweets in the requested range contained "#ddj", or who were replied to or mentioned in those tweets. The network was obtained from the NodeXL Graph Server on Monday, 15 July 2019 at 07:36 UTC.

The requested date range was from Monday, 08 July 2019 at 00:00 UTC through Monday, 15 July 2019 at 00:00 UTC.

The tweets in the network were tweeted over the 6-day, 10-hour, 33-minute period from Monday, 08 July 2019 at 03:03 UTC to Sunday, 14 July 2019 at 13:37 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.
