Stack Exchange — computergraphics.stackexchange.com

The content of computergraphics.stackexchange.com (https://computergraphics.stackexchange.com/), a Stack Exchange question-and-answer site, as published in the Stack Exchange Data Dump of April 2024 on the Internet Archive. The posts table holds 22,490 rows: 8,244 posts (4,024 questions, 4,126 answers, 46 tag wiki excerpts, 46 tag wikis and 2 posts of type 6) and 14,246 comments, written between 4 August 2015 and 31 March 2024. Beside it are 16,788 user accounts, 32,884 votes, 20,805 badges awarded, 251 tags, 25,207 post revisions and 351 links between posts. Every answer keeps the question it answers and every comment the post it was written on, so the threads can be rebuilt. The Internet Archive item describes the dump as anonymised; the votes table names the voter in only 77 rows.
