For many years, I've tended to put key insights of my charts directly in the chart title, to tell readers immediately why I thought they needed to see that data:

BTW, if topics like this are of interest to you (Nerd! Like me 😂), I cover this and many other topics in my Practical Charts course, which I'll be delivering live online on June 2!
