One idea, connected thinking

What is a spider diagram?

A spider diagram, also called a spider map or spider web diagram, places a main topic in the center and connects it to related ideas. Each branch groups a subtopic and short supporting notes, so you can see a subject at a glance.

Use this maker for brainstorming, revision, lesson planning or an essay outline. It creates a concept diagram with editable text, rather than a numerical radar chart.

A clear central topic

Start with one question, subject or project. Keep it specific enough to explore.

Meaningful branches

Choose 2–8 categories, then add up to three supporting points per branch.

A reusable output

Download a sharp SVG for resizing or a PNG for documents and slides.

Spider diagram examples and templates

Choose a starting point, then replace the topic and notes with your own. These examples are actual outputs from this maker.

Make room for your ideas

Use spider diagrams for studying, writing and research

Organize a topic before turning it into a lesson, essay or plan.

Map your argument, supporting evidence and counterarguments before writing the first paragraph.

Keep the meaning clear

Show relationships without overstating them

A spider diagram groups ideas around a topic. Its connecting lines do not establish causation, sequence or numerical magnitude.

Use descriptive headings

Choose categories that help a reader understand the subject. Keep notes short enough to scan.

Check your supporting points

Review facts and sources before sharing. The maker arranges your text; it does not generate or verify evidence.

Pick the right type of diagram

For numerical comparisons across axes, use a radar chart. For overlapping sets, use a Venn diagram.

Less setup, more thinking

Choose a spider diagram template for your next task

Focus on the connections you want to make.

One central idea

See the whole topic

Keep subtopics and details together on one canvas.
