When to use icons

• When space is tight, and you have a long text that can be replaced by an icon.
• When the same action or information is represented in multiple places, using a consistent icon can aid in recognition.
• Icons can draw attention to specific points or categories within your data visualization.

How to use icons

• Ensure the same icon represents the same information or action throughout your visualization or report.
• Choose icons that are straightforward and easily recognizable. Overly complex icons can confuse users.
• Icons should be large enough to be visible but not large to the point they dominate the visualization or make the data visualization feel cluttered.
• Icons can be coloured to match or complement the visualization’s colour scheme. However, ensure that the colour doesn’t alter the icon’s meaning.

Best practices

• Avoid icon overuse. Too many icons can make your visualization look cluttered and confusing.
• Test with your main audience/persona. What might be intuitive to one person might be confusing to another. Gather feedback to ensure your icons resonate with your target audience.
• Consider users with visual impairments. Icons should not be the sole means of conveying information. Pair them with text or tooltips where appropriate.
• Icons are more flexible and easier to use in SVG format
