Question

I want to draw a graph on web. Many users in web suggest Graphviz to me.

How can I use Graphviz in an asp.net application? What is the Graphviz render process in web?

Answer 1

You may use QuickGraph API - C# wrapper for the GraphViz graph generator. (Code project article - QuickGraph : A 100% C# graph library with Graphviz Support).

What is the Graphviz render process in web?

Using P/Invoke methods you may render in-memory image. Have a look at Rendering an in-memory Graphviz image with C# and Graphviz C# Sample .

Answer 2

You can use the Graphviz Dll's using Interop to do that.. Please see this post : http://pldineshtech.blogspot.com/2012/08/using-graphviz-library-in-net.html

Basically you will be calling this method -> Graphviz.RenderImage(), create an image and transmit it back to the client.

Answer 3

This fairly new library called Graphviz.NetWrapper allows you to build graphs in C# code, compute a layout using the graphviz library, and read the layout information (like positions etc) back out using C#.

To draw a graph in a webpage you could send this layout information eg in JSON over the web and draw using eg D3 JS.
