The Importance of Donut Charts in Looker Studio Dashboards
A donut chart is a variation of the pie chart, distinguished by its hollow center, which enhances readability and allows for additional data representation within the inner space. In business dashboards, donut charts play a crucial role in summarizing complex datasets in an easily digestible format.
Here are some key reasons why donut charts are essential for Looker Studio dashboards:
Quick Insights at a Glance
Decision-makers can quickly gauge the proportions of different categories within a dataset without deep diving into complex tables or reports.
Enhanced Readability
The hollow center prevents data overcrowding, making it easier to distinguish between segments, especially when compared to traditional pie charts.
Effective for Business Performance Metrics
Donut charts are excellent for tracking KPIs like revenue share by product category, customer segmentation, or marketing channel performance.
Space Efficiency in Dashboards
Looker Studio dashboards often display multiple charts and graphs. Donut charts help conserve space while maintaining data clarity.
Better Comparisons Across Data Points
Unlike bar charts, which may require more space, donut charts provide a concise yet effective way to compare proportions.

1. Customizable Colors
Users can assign specific colors to different segments, ensuring brand alignment and improving clarity.
2. Dynamic Filtering and Interactivity
With Looker Studio, users can filter and interact with donut charts to drill down into specific data subsets.
3. Data Labeling and Formatting

5. Combining with Other Charts
Users can integrate donut charts with other chart types (e.g., bar charts and line graphs) for deeper analysis.
Donut Chart vs. Other Chart Types
While donut charts are useful, they are not always the best choice for every dataset. Here's how they compare with other visualization types:
Donut Chart vs. Pie Chart
Similarities: Both display proportions of a whole.
Differences: Donut charts have a hollow center, improving readability and allowing for additional data representation.
Best Use Case: Donut charts are preferable for dashboards due to their cleaner design.
Donut Chart vs. Bar Chart
Similarities: Both can display categorical data.
Differences: Bar charts are better for comparing exact values across categories, while donut charts excel in showing relative proportions.
Best Use Case: Use a bar chart when absolute values are more critical than proportions.
Donut Chart vs. Line Chart
Similarities: Both help visualize trends over time.
Differences: Line charts are better for showing trends over time, while donut charts are best for displaying proportions at a single point in time.
Best Use Case: Line charts are ideal for tracking trends, while donut charts are better for static comparisons.
Best Example of Data Presented in a Donut Chart
A great example of data best presented in a donut chart is website traffic sources. Businesses with an online presence often need to analyze where their website traffic is coming from (e.g., organic search, paid search, social media, referrals, direct traffic, email marketing, etc.).
By using a donut chart in Looker Studio, a marketing team can quickly visualize the distribution of traffic sources and determine which channels are performing best. The color-coded segments make it easy to distinguish between traffic types, while the percentage labels allow marketers to see at a glance how their traffic is distributed.
