Creating a treemap in Prezi Design

Treemap__2_.png

Treemaps offer a great way to display your data in a hierarchical view and compare different categories via their size. Since the information is displayed in rectangles that vary in color and size, treemaps make it easier to see patterns that couldn’t be identified straight away by simply looking at the raw data.

With Prezi Design, you can easily create a treemap of your own, add the data you want to visualize, and customize the chart to your specific needs. Here's how!

Adding a treemap to your project

  1. From the Prezi Design editor, select Add chart in the left-side toolbar.
  2. Find the treemap (scroll the list or use the search bar at the top) and click on its thumbnail or drag and drop it right onto the canvas.

Adding data to the chart

  1. To access the chart's datasheet, double-click on it or select Edit data in the top right corner of the editor.
  2. You'll see some placeholders in the datasheet. Here's how you should format it:
    • Use the first column to enter the names of the values you want to visualize in the rectangles.
    • Use the second column to enter the values of each entry. The size of the rectangles will depend on the values you enter here.
    • You can create additional tabs on the treemap by entering additional values in the following columns.

It's also possible to add data by uploading XLS, XLSX, and CSV files, connecting your chart to a Google Drive document, connecting your chart to a JSON feed, as well as connecting to an online database.

Customizing the treemap

You'll find all of the editing options in the settings panel on the right side of the editor. Change the chart's colors and fonts, sort the entries, adjust the data format, and do much more.

  • Chart properties. Choose to show or hide the chart's values, give viewers the option to download the data you've visualized, change how the values are sorted, and do much more.
  • Color. Change the colors of the treemap's rectangles.
  • Fonts. Set the font for your chart, and adjust its color and size.
  • Tooltips. Enable or disable the tooltips.
  • Data format. Adjust the numeric format of your data, add prefixes/suffixes to the values.
  • Accessibility. Make your chart accessible to viewers using screen readers.

Making the treemap interactive

With Prezi Design, you can make your chart more interactive by adding URL links, page links, and links to specific chart/map tabs.

  1. Double-click on the chart or select it and expand the Edit data tab on the right.
  2. Right-click on a cell of a specific value and select Add/change link.
  3. Select one of the available options and add the link. Then, select Apply.

Downloading and/or sharing the treemap

Downloading the chart

To download the project you're working on, select the Download option in the top right corner of the editor. Next, choose one of the available file formats at the top and select Download to save the project to your computer.

If you'd like to download the chart straight from the editor, right-click on it on the canvas, select Export as... in the context menu, and pick the file format.

Learn more in the article about downloading your content in Prezi Design.

Sharing and embedding the chart

Select Share in the top right corner of the editor to access the project's privacy settings. Choose whether you want to keep it private and use a private link to share the content with others or make it public and visible on search engines. Read more in the article about changing privacy settings in Prezi Design.

Best practices for creating treemaps

  • Start with clean data and a clear message. Treemaps can often involve a lot of data, so it's essential to know what exactly you want to highlight.
  • Use bright, contrasting colors so each region is easily visible. But, remember to avoid the 'rainbow effect'. Choose your colors wisely.
  • Label each region appropriately with text or numbers. This makes it easier for the viewer to evaluate your treemap quickly, without error.
  • Avoid cluttering your treemap with too many boxes. Treemaps can contain any number of boxes, but space is limited! You don't want your treemap to be hard to read.
