Design bar charts to compare AI metrics across countries, sectors, and
Use bars for categorical comparisons. Keep baselines at zero unless clearly noted. Avoid 3D or heavy decoration.
Use horizontal bars for long labels (country names) and vertical for time buckets.
Provide source and last-updated timestamp below the chart.
Y-axis for categories (horizontal bars) or values (vertical bars); X-axis for values or time. Include gridlines with low contrast.
Grouped bars for comparing multiple series per category.
Normalized 100% stacks for share comparisons across countries.
Place value labels at bar ends when space allows; otherwise use tooltips. Keep axis ticks minimal and consistent.
Use brand palette with strong contrast. For multiple series, use distinct hues; for single series, use a single hue with tint for inactive states. Avoid relying solely on color—use patterns for accessibility.
Frequently asked questions
How can I ensure sufficient contrast between the bars, labels, and gridlines in my bar chart?
Ensure AA contrast on bars, labels, and gridlines. Keyboard navigation should move across bars; Enter/Space opens tooltip or pin. Provide data table download (CSV) and text summary of the key finding.
What adjustments should I make to switch to horizontal bars when viewing the chart on a narrow screen?
Switch to horizontal bars on narrow screens. Reduce tick density and wrap labels. Use touch-friendly tooltips and larger hit areas. Consider mini-sparklines for dense dashboards.
