Diagram Presentation Templates and Slides – Free & Premium for PowerPoint, Canva & Google Slides

✨ Build clear, visual-first decks with editable diagram templates for PowerPoint, Google Slides, and Canva. Start with Venn diagram layouts (2–6 sets) for intersections and comparisons—available as Google Slides Venn diagram templates and print-friendly Venn diagram templates for Google Docs.

Explain causes and effects using fishbone diagram (Ishikawa) slides. Map categories, sub-causes, and evidence; then turn findings into actions. For processes and frameworks, use cycle diagrams (3–6 steps), funnel diagrams for staged drop-off, and pyramid diagrams for hierarchies and priorities.

All diagrams are editable—swap colors, add icons, and resize nodes while keeping line weights and spacing consistent. Paste data from Sheets/Excel, or duplicate steps for longer flows. Explore free and premium packs, including diagram templates for Google Slides with matching styles across Venn, funnel, pyramid, and process pages.
