18 Diagram Categories to Cover Major Structures and Processes in PowerPoint

18 Visual Diagram Categories to Cover Major Structures and Processes in PowerPoint

Imagine you are working on an important presentation. You are aware that a visual slide content is much better for your audience than pure text. So you try to use visual diagram graphics where possible. However, you run out of creative ideas for some topics – how to illustrate a gap or give a fresh look to the agenda slide, for example.

I’ve been there. With every presentation project, I face this challenge – how to quickly pick the best visuals for particular slide content. How to save time and avoid designing visuals from scratch.

The answer to my slide work productivity challenge was to build a slide deck with universal visual diagrams I can use again and again. This deck helps me to get most of the PowerPoint visual power.

To help you and myself, I decided to gather all the essential diagrams we used in our design projects over the last years. To create one big set of slides that would cover all content types – from lists and agendas to timelines, data visualizations, synergies and hierarchies.

Check the collection we designed of all common diagrams, see an overview of Flat Ultimate Infographics Bundle.

Diagram as a powerful and universal slide visual

To make your presentation slide visually appealing, you simply need to replace text information by some infographics. You can illustrate content by adding a stock photo, but that serves only as an addition, not a replacement of text. To fully replace the text by visuals, I suggest you try using diagrams.

What is a diagram?
A graphical representation of qualitative information through simple shapes (arrows, rectangles, circles). Diagram expresses relations such as dependency, flow, overlap or hierarchy of concepts.

18 diagram categories organized into 3 areas to cover almost any content

After collecting all the essential diagrams, my challenge was to organize it in a simple yet logical way.
To give users a way to quickly find the proper visual for their business content.

I spend several hours moving pieces around and here you can see the result of my work – an overview of diagrams organization I came up with:

Altogether our designers’ team gathered 18 categories of diagram visuals.

As you can see, finally I grouped them all into three main areas:
List diagrams – to present agenda or features in a visual way
Structure diagrams – to show hierarchies and other dependencies
Flow charts – for processes, timelines and procedures visualization

Additionally, I added two special categories that cover data visualization and abstract business concepts:
Data and Key Performance Indicators with creative table and chart graphics
Business Concepts illustrations with various visual metaphors such as DNA helix or bridge.

Putting it all together took us a few weeks. Designing, unifying, quality testing of over 200 diagrams is not easy. But we did our best to create one consistent set anybody can easily use to make his or her slides look professional.

Our quality criteria were:

  • Have a well-organized set of slides, by information topic, so it’s easy to understand them and use
  • Consistent style of all graphics. When you pick up any graphics, it will look professional and not like randomly gathered pictures from various sources
  • A universal style that fits any branding. Here we decided on a modern flat graphical style with vivid colors, that is simple yet appealing.
  • Ensure all diagrams are editable so you can add or remove items and modify colors to match your company’s visual identity – replacing template color or changing any shape color.

How to choose matching visual diagram for your text slides

Here’s the most interesting part. Let’s see how you can use those diagram types to cover your slide content.

Firstly, look at slide content and try to identify what information type you have there. What is the message your slide wants to convey? Is it a list of features? Is it a sequence of steps? Try to see the key elements and what are relations between them – are they an independent list or do you have there some kind of a hierarchy?

If you want to dig deeper into possible information types, I recommend reading a book by Dan Roam – On the Back of the Napkin. Another book you can check is Nancy Duarte’s SLIDE:OLOGY that also contains a list of information types.

Here’re a few examples of visualization of our three information areas.

Lists to replace bullet-points or make cool PowerPoint agenda slide

When you have a list of 3-10 bullet-points, use a visual list diagram to replace plain text. For a better visual power, try to illustrate your points with a specific icon for each topic.

You can make your list look more unique and creative by using paintbrush graphics like on this example:

Double lists to compare categories visually

To create a nice visual comparison slide, use a two-sided graphic layout with e.g. DNA or Scale picture in the center.

On the slide above you can see scale visuals, you can use when evaluating two options and their features. A scale can show what option is heavier – that means better or winning.

Structures you can express visually by pillars and Venn diagrams

If you present an overlap of concepts or a common area, Venn diagrams are the classical visual structure to be used. Here’s how we redesigned the Venn diagram:

On the other side, if you want to show that your idea is built on strong and several foundation concepts, consider pillar diagram:

Central lists to show idea-centered concepts

Let’s say you want to show your organization is customer-centered. I’d use here a customer element as a centric element and all other items put around it.

Representing hierarchy

If you have a certain hierarchy on your slide, consider showing it with layer diagrams where you put each hierarchy level into separate a layer.

Depending on your content, try using a vertical set of layers or a pyramid. Onion diagrams can be good visual if your slide idea is based on a central core covered all over by other layers. Or use the iceberg metaphor to express visible and hidden layers:

Other creative visual diagram ideas

Besides those classical diagrams I mentioned above, there are many others – matrixes, flow chart timelines, funnels, you name it.

Here you can see a creative visualization of a roadmap with business strategy milestones and definition of company vision goal.

Personalize diagrams with icons – but stay consistent

Once you have found and selected a diagram that best represents your slide content, don’t forget to make it look professional. Follow those three basic design rules:

  1. Ensure graphics are consistent with the rest of your presentation. Use the same color palette. You can modify the diagram filling, apply your company color.
  2. Make sure the slide is not overcrowded. Have enough whitespace – margins around diagrams and texts.
  3. Personalize your illustration by adding a symbol to each key element. That will make the information easier to understand. Remember about using one style of icons e.g. Simple Flat Icons or Light Outline Symbols. Don’t mix them, because that looks unprofessional.

We added the most common business symbols that you can copy into your diagram inside our slide-deck.

Take advantage of reusable visuals

I hope the examples above give you inspiration on how you can replace texts in a presentation by powerful visuals. You can start creating your own diagram set, using PowerPoint shapes and organizing them in a way that matches your presentation topics.

Or you can speed up the process and reuse the diagram collection we put together. We did our best to make sure all diagrams are unified, consistent and easy to be edited.

Now I believe it will help others to make their presentations more attractive and more effective in conveying their message.

All examples above are based on the PowerPoint diagram set we have designed. It contains over 200 diagram slide layouts and tens of vector icons that you can copy to your presentation, modify their structure and style, write your text inside.
