Use case(s) (list the steps that you performed to discover that problem, and describe the actual underlying problem which you want to solve. Do not describe only a solution):
When we go to a campaign, e.g. https://isa.toolforge.org/campaigns/230, there's a link to the full stats, e.g. https://isa.toolforge.org/campaigns/230/stats, which ... is kinda underwhelming. it's neither full nor giving any meaningful information that isn't in the main campaign page itself, rather just a pie chart of the same basic stats. (This is talking about the web version, not the downloadable CSV, which is broken anyway T325735, so I didn't know if by "full stats" it means the CSV or the pie chart)

Feature summary (what you would like to be able to do and where):
I expect to see many wonderful stats (text or visual) like:

• total days running
• total contributions, contributions per day
• graph chart of contributions per day, so we can see the peak days
• how many people contributed, the average contribution per contributor, average contributions per day
• how many structured data added, removed, changed
• how many distinct files get new structured data
• list of files with the most structured data added
• list and links to the most used structured data / wikidata items
• links to user contributions (instead of links to their profile pages), better yet, link to user contributions for this particular campaign (after all, you guys put an automatic tags to each contributions. You can use 3rd party tool as well, like hashtags.wmcloud.org, but you need to reformat the automatic tags first)

This list by no means is exhaustible

Benefits (why should this be implemented?):

It's a cure for a datajunkie. jk.

Good stats will always useful for a lot of purpose. GLAM Indonesia already held 8 campaigns so far. We could use some auto generated stats for our campaign result reports.

This is the manual stats I made last semester:
