FAQ
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.
How do I share or export my network diagram?
Once your diagram is ready, you can download it as a PNG or SVG image, copy a shareable link, or use an embed code to add it directly to a website or blog. Sharing options are available on all plans, with embed codes on Plus and Pro.
Is MakeCharts suitable for large network diagrams?
Yes. MakeCharts supports zoom and pan interactions so you can navigate large networks without losing clarity. You can add as many nodes and relationships as your network requires and explore the diagram at any zoom level.
Do I need to sign up to make a network diagram?
No sign-up is required to start. You can create and download a network diagram immediately on the free plan. Creating an account unlocks saved diagrams, AI credits, and access to additional features like file upload and embed codes.
