Chart design best practices

Apply these essentials as you iterate on your visualization to deliver data stories that are clear, credible, and persuasive.

Start with the question

Decide what insight your audience needs before picking a chart. Use comparison charts for rankings, trend charts for time, and composition charts for parts of a whole.

Highlight the key takeaway

Use annotations, contrasting colors, or reference lines to guide attention to the most important datapoint without overwhelming the viewer.

Keep labels clear and concise

Choose intuitive axis titles, round numbers to meaningful precision, and avoid clutter by limiting the number of series displayed at once.
