Chart Mysteries Solved: That Little Box of Explanations? It’s Called a Legend!

Ever stared at a chart, wondering what those colorful squares or lines meant? You’re not alone! It’s like trying to read a secret code, right? Well, that codebook, that little box of labels, it has a name: the “legend.” Think of it as your chart’s translator, turning those visual clues into plain, understandable info. Let’s dig into why it matters, and how to make sense of it all.
