What are the key elements to consider when creating informative and visually appealing graph captions?

When creating informative and visually appealing graph captions, consider including a clear and concise title that summarizes the main point of the graph, providing context for the data presented. Use descriptive labels and units for axes and data points to ensure clarity. Incorporate a brief explanation of the data trends or patterns shown in the graph. Additionally, choose a visually appealing font and layout that complements the graph design without overwhelming it.
