How to Make a Network Diagram Online
From blank canvas to finished diagram in three simple steps.
Add Your Nodes
Enter the names of the people, systems, or entities you want to map. Choose a shape for each node to distinguish different types at a glance.
Add nodes: 'Alice', 'Bob', 'Carol', 'Team Lead' — pick circle for people, square for teams.
Define Relationships
Connect your nodes by selecting a 'From' and 'To' for each relationship. Add as many connections as your network requires.
Connect: Alice → Bob (collaborates), Alice → Team Lead (reports to), Bob → Carol (mentors).
Set the Center and Style
Choose a root node to anchor the view, adjust font size, and toggle zoom. Your diagram updates instantly as you configure.
Set 'Team Lead' as root node to see the full reporting hierarchy radiating outward.
Export and Share
Download your finished network diagram as PNG or SVG, copy a shareable link, or embed it on your website.
Export as PNG for a slide deck or grab the embed code for your company wiki.

Frequently Asked Questions
What is a network diagram maker?
A network diagram maker is an online tool for visualizing relationships between people, systems, or entities as nodes connected by lines or edges. MakeCharts lets you make network diagrams online without any design or technical experience — just add your nodes, define the connections, and your diagram renders instantly.
How do I make a network diagram online for free?
Open MakeCharts, select the Social Network chart type, add your people or entities as nodes, and connect them with relationships. The diagram renders live as you build it. No sign-up or payment is needed to create and download your first network diagram.
Can I make a network diagram online using AI?
Yes. MakeCharts includes AI-powered chart generation. Simply describe your network in plain language — for example, 'Map my project team with Alice as the lead connected to Bob and Carol' — and the AI will generate a complete social network diagram for you. Free AI credits are included on every account.
What is the difference between a network diagram and an org chart?
An org chart shows a strict top-down hierarchy, while a network diagram (or social network diagram) maps free-form, multi-directional relationships between any number of nodes. Network diagrams are better for showing peer connections, influence networks, or systems where relationships are not strictly hierarchical.
Can I customize node shapes and styles in my network diagram?
Yes. Each node in MakeCharts can be styled individually with shapes including circle, square, rounded rectangle, hexagon, and cloud. You can also adjust font size and set any node as the central root to change the visual perspective of the whole diagram.
