PURPOSE Charts help explain patterns, comparisons, and trends. CHOOSE THE RIGHT CHART Use bar charts for comparisons, line charts for trends, and simple pie charts only for clear parts of a whole. MAKE IT CLEAR Use a direct title, readable labels, simple colors, and minimal gridlines. FOCUS THE MESSAGE Highlight the point the audience should take away instead of showing every possible data detail. CHECK Make sure the chart is accurate, sourced when needed, and readable from the back of the room.
