In today’s data-centric world, business presentations have evolved well beyond simple slides and stock graphics. Modern presentations must communicate complex data in ways that are both visually engaging and easy to understand. This is where data treemaps come in—a powerful data visualisation tool that can elevate your presentations, allowing audiences to grasp important insights at a glance. In this article, we’ll dive into treemaps, exploring their types, benefits, limitations, and tips on how to create effective treemaps that enhance your message.
Understanding Treemaps in Data Visualisation
What is a Treemap?
A treemap is a data visualisation tool that uses nested rectangles to display hierarchical data. Each rectangle’s size represents a specific data value, and colour often indicates another variable or category. This unique visual format, also called treemapping, provides a clear overview of data relationships and patterns, making it ideal for audiences to understand complex information quickly. Treemaps are an excellent choice when conveying the relative significance of various data points in a presentation.
How Are Treemaps Used in Presentations?
Data treemaps are becoming an increasingly popular data visualisation tool for presentations due to their capacity to present large datasets in a clear, digestible format. Whether you’re presenting financial results, product performance, or website analytics, treemaps can make your data come alive. By offering a visually intuitive snapshot of the data, treemaps enable your audience to focus on the key trends and insights that matter most.
Types of Data Treemaps
Different types of treemaps can be used to display data, each with a unique layout and visualisation style. Here’s a look at the most common types and when to use them.
Slice-and-Dice Treemaps
The slice-and-dice treemap divides the display area into alternating horizontal and vertical sections, clearly illustrating data hierarchy. This straightforward approach is ideal for presenting information with well-defined categories.
Squarified Treemaps
Squarified treemaps aim to make the rectangles as square-shaped as possible. This reduces wasted space and enhances visual comparison across different data segments, making it easier to analyse complex data.
Strip Treemaps
Strip treemaps arrange rectangles in rows or columns and are ideal when data order isn’t critical. They work well for highlighting individual data sizes in a neat, organised format.
Cluster Treemaps
Cluster treemaps group related data points in a visually cohesive way, making it easier to spot connections and trends. This approach is effective for examining relationships within large datasets.
Circular Treemaps
In circular treemaps, data is arranged in concentric circles rather than rectangles, with each ring representing a level in the hierarchy. While visually appealing, circular treemaps can be more challenging to interpret accurately.
Voronoi Treemaps
Voronoi treemaps use unique shapes based on proximity data points, creating visually distinct sections. While aesthetically interesting, they may be harder to interpret quickly.
Choosing the right treemap data visualisation tool depends on factors such your data’s complexity and your presentation’s goals. A well-chosen treemap can elevate the impact of your data and make it easier for audiences to grasp the key points.
Treemaps in PowerPoint Presentations
For most PowerPoint presentations, slice-and-dice and squarified treemaps are popular options. Both styles allow you to convey hierarchical data clearly and concisely, making them suitable for most business presentations. When creating treemaps in PowerPoint, consider your presentation’s objectives, the complexity of the data, and the audience’s familiarity with treemaps. Clear labels and notes help viewers understand the data’s structure and significance. For guidance on making engaging, data-rich presentations, check out our blog on Presentation Design Rules.
Key Advantages of Treemaps in Presentations
Enhanced Visual Appeal
Treemaps are visually distinctive and captivating, grabbing your audience’s attention and keeping them engaged throughout the presentation. This impactful visual element helps strengthen your message and leaves a memorable impression on your audience.
Effective Use of Space
When you need to present extensive data within limited space, treemaps provide an ideal solution. Unlike traditional charts that may become cluttered, treemaps allow you to display large datasets clearly and concisely, maximising slide space without overwhelming the audience.
Ideal for Hierarchical Data
Treemaps are designed to display data with multiple levels, making them excellent for categorised information. They make it easier for audiences to grasp complex relationships and spot trends within hierarchical data structures.
Quick Data Interpretation
Treemaps provide a visually intuitive means for viewers to assess the importance of different data points quickly. This supports rapid data comprehension, allowing your audience to focus on your presentation’s broader insights and implications.

Limitations of Treemaps in Data Visualisation
Limited Data Precision
While treemaps are excellent for visualising relative values, they may not be suitable when precision is required. The layout’s design can sometimes make it difficult to gauge exact values, in which case a different visualisation format may be more effective.
Potential for Misinterpretation
Treemaps may be an unfamiliar data visualisation tool to some audiences. This leads to potential confusion, especially without clear guidance. Always take time to explain the treemap format and offer a brief background to help audiences interpret the data accurately.
Complexity with Large Datasets
For complex or extensive datasets, treemaps can become cluttered, making it challenging for audiences to identify meaningful trends. In such cases, consider simplifying the dataset or using supplementary visuals for a clearer representation.
Tips for Creating Effective Treemaps
Select Appropriate Colours
Colour choices can significantly influence the readability and effectiveness of your treemap. Use distinct colours for different categories and consider using gradient tones to represent value differences clearly. This approach helps audiences quickly identify significant data trends.
Keep it Simple
Simplicity is key to effective treemap design. Avoid overcrowding your treemap with too much information, making it harder for viewers to interpret. Focus on essential insights and ensure that your treemap is easy to read and understand.
Use Clear Labels and Annotations
Adding readable labels and annotations ensures that viewers can follow the treemap’s structure and understand its meaning. This clarity lets them focus on the presentation’s main points and appreciate the value of the data being presented.
