How to create graphs in Delphi application

I need to create graphs on the fly about specific proce开发者_JAVA技巧ss, with some informative texts and colors.

In the Unix world there's Graphviz including 'dot' for layout generation, is there something similar which could be used with Delphi?

I'm using Delphi 2007.

Also Python alternative could be considered, but I'd prefer pure Delphi in this case.

You can use SimpleGraph from DelphiArea.
A have test and use it and it's a great component. Freeware with sources.

Regards.

@Harriv, You can try WinGraphviz wich is a COM Wrapper for Graphviz.

TMS also have a diagram studio and a workflow studio

and a post about the ways to make it

Steema Software has a Delphi VCL TeeChart product that you may find interesting depending on your needs.

I have experimented with the trial version of this. I was able to create some very nice looking graphs. I was also able to use a shape file of the counties in our state to show statistics per county in a 3D view where the counties with the highest values stood out to the user.
