Revolutionize Data Visualization in Excel: Mastering Treemap and Sunburst Charts

In the dynamic realm of data analysis, Microsoft Excel continues to evolve, introducing powerful features that cater to the needs of analytical minds. Treemap charts, also known as mosaic charts, and Sunburst charts are recent additions to Excel's arsenal, offering an innovative way to visualize hierarchical data. Hierarchical data structures are designed to organize information with multiple one-to-many relationships, establishing a hierarchy where a parent can have multiple children, but each child has only one parent.

Let's delve into the world of Treemap and Sunburst charts, exploring their utility in transforming complex hierarchical data into insightful visual representations. To exemplify their prowess, we'll utilize the file "vishalseptember19.xlsx," containing hierarchical data showcasing a bookstore's revenues from different types of books.

Understanding Hierarchical Data

Hierarchical data structures are particularly useful when dealing with complex relationships. For instance, consider tracking product sales based on quarters, months, and weeks. Here, the quarters act as parents, each having multiple children (months), and each month, in turn, having its set of children (weeks). This hierarchical organization allows for a comprehensive understanding of the data's structure.

Another scenario involves a bookstore, where book genres serve as parents, such as children's books, art and photography books, and more. The children of the art and photography category might be crafts and coffee-table books, while children's books could have children's age categories like Age 3-5 and Age 6-8, each further branching into specific subcategories. This hierarchical organization provides clarity in navigating through diverse genres and sub-genres.

Creating a Treemap Chart

The Treemap chart is a visual marvel that succinctly summarizes sales data for each product category. Let's walk through the steps to create an impactful Treemap chart.

  • Select Data Range:
  • - Choose the range A1:D29 in the Treemap worksheet.

  • Insert Treemap Chart:
  • - Click on the Insert Hierarchy chart icon and select the Treemap chart option.

  • Format Data Series:
  •  - Right-click on the chart and select Format Data Series. Opt for Banner labels.

  • Customize Data Labels:
  • - Navigate to Chart Design, Chart Element, Data Labels, More Options, and check Values. This step ensures that the Treemap chart displays the corresponding sales values.

    The resulting Treemap chart vividly portrays the relative size of each product's sales, with the size of rectangles directly proportional to sales figures. A quick glance reveals that Children's books dominate sales in this visualization.

    Creating a Sunburst Chart

    The Sunburst chart offers an alternative perspective on summarizing hierarchical data. It represents sales in a circular fashion, breaking down into rings or circles based on the hierarchy.

  • Select Data Range:
  • - Highlight the cell range A1:D29 in the Sunburst worksheet.

  • Insert Sunburst Chart:
  • - Utilize the Insert Hierarchy chart icon and opt for the Sunburst chart.

  • Insert Data Labels:
  • - Follow the same procedure as the Treemap chart to insert data labels.

    The resulting Sunburst chart showcases a circular representation where the size of rings corresponds to total sales figures.

    Comparing Strengths of Treemap and Sunburst Charts

    While both charts offer unique insights, they excel in different aspects. The Treemap chart excels at illustrating the relative size of product sales, making it easy to identify the bestselling categories. On the other hand, the Sunburst chart shines in breaking down rings into their component pieces, providing a detailed hierarchical view. It may not be as effective in portraying relative sales sizes, but its strength lies in elucidating the breakdown structure.

    Embrace the Power of Data Visualization in Excel

    As Excel continues to empower users with cutting-edge features, mastering the art of visualizing hierarchical data through Treemap and Sunburst charts becomes a valuable skill. Whether you're tracking sales, exploring organizational structures, or analyzing complex relationships, these charts offer a visually appealing and insightful way to navigate through intricate data hierarchies.

    As you embark on your data visualization journey, remember that the key lies not just in understanding the data but in conveying its story effectively. Treemap and Sunburst charts serve as your dynamic companions, transforming raw data into a visual narrative that speaks volumes. Excel's evolution is a testament to its commitment to simplifying complex tasks, offering users the tools they need to elevate their data analysis game.
