Questions tagged [charts]

Charts are a graphical representation of data, most often in the format of a graph or diagram. Use this tag for questions about using a charting library API.

Charts are a graphical representation of data, using dots, lines, bars, geometric figures or other graphical elements. They can help you visualize vast amounts of data in a way that is easily understood. Similar to the saying "A picture is worth more than 1000 words", one may say "A chart is worth more than 1000 reports" ...
