Design Principles for Visually Appealing Data Dashboards

Data dashboards are powerful tools for communicating insights, trends, and performance metrics. To maximize their effectiveness, it is crucial to design them with visual appeal and clarity. This article presents a comprehensive guide to creating visually appealing data dashboards, drawing upon insights from reputable sources such as ELVTR, Geckoboard, and LinkedIn.

Key Facts

Choose a design layout and color scheme: Select a clear layout that helps your audience navigate the dashboard easily. Use a color scheme that is easy on the eyes and supports the overall theme. Avoid clutter and unnecessary elements that may distract from the data. Consider using a grid system to organize your dashboard into sections.
Focus on useful metrics: Ensure that the metrics you display are relevant and provide value to your audience. Align them with your goals and key performance indicators (KPIs). Avoid adding too much information that may detract from what’s important. If necessary, create multiple dashboards to accommodate different sets of metrics.
Reduce visual noise: Aim for a good data ink ratio, which means using as little non-data ink as possible. Remove unnecessary grid lines, icons, color, labels, or any elements that don’t communicate data effectively. Decorative elements may initially grab attention but can become distracting over time.
Use appropriate visualizations: Choose visualizations that clearly and efficiently communicate your data. Avoid using pie charts and area charts, as people are not good at comparing spatial areas. Stick to a combination of numbers, bars, lines, and tables. Consistency in visualizations and layouts between groups enhances readability and aesthetics.
Position information logically: Group related metrics together to make them easy to find. Experiment with different grouping methods, such as by metric, product, brand, campaign, region, team, or time period. Provide clear titles for each group to enhance visibility.
Create hierarchy and emphasize important information: Use size and position to highlight the most important information and downplay less frequently viewed metrics. Consistent sizes and clear relationships between elements help create patterns and visual flow. The top left corner of your dashboard is the best location to draw attention first. Don’t be afraid of empty space; it’s better to leave a gap than to fill it unnecessarily.
Provide context and clarity: Include past data, such as the same metric for the previous day or a chart showing how the metric tracks over time. Add the average or previous highs and lows for comparison. If you have goals, include the target and current progress. Use clear and concise labels that are self-explanatory. Abbreviations and symbols can be used if your audience understands them. Avoid jargon, acronyms, and vague terms that may confuse your audience.
Iterate and gather feedback: Continuously seek feedback from your team to improve your dashboard. Identify what they find most useful and least useful, and make adjustments accordingly. Regularly review your dashboard to ensure it effectively communicates the intended information. Update your dashboard as goals and priorities change.

Choose a Design Layout and Color Scheme

A well-structured layout and color scheme are essential for enhancing the user experience and readability of a dashboard.

Utilize a clear layout that facilitates easy navigation and understanding of the data.
Select a color scheme that complements the overall theme and is pleasing to the eye.
Avoid excessive clutter and unnecessary elements that may distract from the data.
Consider implementing a grid system to organize the dashboard into distinct sections.

Focus on Useful Metrics

Prioritize the inclusion of relevant and valuable metrics that align with the goals and key performance indicators (KPIs) of the target audience.

Ensure that the displayed metrics provide actionable insights and contribute to decision-making.
Avoid overwhelming the dashboard with excessive information that may detract from the most important aspects.
Create multiple dashboards if necessary to accommodate different sets of metrics for various purposes.

Reduce Visual Noise

Aim for a high data ink ratio by minimizing non-data elements that do not contribute to the effective communication of information.

Eliminate unnecessary grid lines, icons, colors, labels, and other decorative elements that do not convey data.
While decorative elements may initially attract attention, they can become distracting over time.

Use Appropriate Visualizations

Select visualizations that clearly and efficiently communicate the intended data.

Avoid using pie charts and area charts, as people generally struggle to compare spatial areas accurately.
Opt for a combination of numbers, bars, lines, and tables for effective data representation.
Maintain consistency in visualizations and layouts across different sections of the dashboard to enhance readability and aesthetics.

Position Information Logically

Organize related metrics into groups to facilitate easy identification and understanding.

Experiment with different grouping methods, such as by metric, product, brand, campaign, region, team, or time period.
Assign clear titles to each group to improve visibility and navigation.

Create Hierarchy and Emphasize Important Information

Utilize size and position to highlight key information and prioritize less frequently viewed metrics.

Apply consistent sizes and establish clear relationships between elements to create visual flow and patterns.
Position the most important information in the top left corner of the dashboard to capture immediate attention.
Embrace the use of empty space; it is preferable to leave gaps rather than overcrowding the dashboard unnecessarily.

Provide Context and Clarity

Enhance the comprehensibility of the dashboard by providing context and clarity to the data.

Include historical data, such as previous day’s metrics or time-series charts, to provide a comparative perspective.
Incorporate averages, highs, and lows for reference and context.
Use clear and concise labels that are self-explanatory and easily understood.
Employ abbreviations and symbols judiciously, ensuring that the audience is familiar with their meanings.
Avoid jargon, acronyms, and vague terms that may confuse or mislead the audience.

Iterate and Gather Feedback

Continuously seek feedback from users to refine and improve the dashboard.

Identify aspects that are found most and least useful, and make adjustments accordingly.
Regularly review the dashboard to ensure that it effectively communicates the intended information.
Update the dashboard as goals and priorities evolve to maintain its relevance and effectiveness.

Conclusion

By adhering to these design principles and incorporating best practices, you can create visually appealing and informative data dashboards that effectively communicate insights, trends, and performance metrics to your target audience. Regularly seek feedback and iterate on your designs to ensure that they continue to meet the evolving needs of your users.
