WordPress runs roughly 43% of all websites, and every one of those sites has the same problem: adding a small piece of live data — how many people are reading, which countries visit, where people click — usually means installing a plugin you'll have to maintain, update and trust.
No plugin. WordPress accepts raw HTML in a Custom HTML block, which is all this needs. Every widget below is one snippet, pasted in once. Pick one and the page tells you the exact menu path for WordPress, the gotchas, and what to do if you're on an older theme or a page builder.
