Inspired a bit by the work of Jeremy Keith and others, I’ve recently been playing around with some sparklines on my website. While tinkering around with things, mostly on the back end of my site, I’ve tried out several WordPress-specific plugins, both to see how they’re built and the user interfaces they provide. 
There are several simple plugins for adding sparklines to WordPress websites including:

Activity Sparks plugin by Greg Jackson which adds some configurable functionality for adding sparklines to WordPress sites including for posts and comments as well as for tracking categories/tags.

Sparkplug by Beau Lebens has similarity to the Activity Sparks plugin (above), but with a slightly older looking and somewhat less refined output.

At present, I’m using the Activity Sparks plugin in my sidebar to display the recent activity on my site in terms of my posting frequency and the comment frequency. One chart provides the daily activity on my site over the past 3 months while the other provides the monthly activity over the past 5 years.
When on particular category pages, you can see the posting velocity for those particular categories in these respective time periods. While on the homepage and other miscellaneous pages, you can see the aggregate numbers for the website.
Generally I don’t care very much about the statistics, but in aggregate they can sometimes be fun to look at. As quick examples, I can tell roughly by looking at the 5 year time span when I added certain posting features to my website or that time my site got taken down by HackerNews.

hat tip to Khürt Williams who reminded me I needed to circle back around and finish of a small piece of this project and document it.
