Question

How can I draw flow chart using LaTeX?

Answer 1

Tikz is a good graphics library to do this (directly in Latex), here is an example of a flowchart made with it.

Answer 2

I know it's not strictly using LaTeX, but the Graphviz suite of tools is pretty neat.

From the description:

The Graphviz layout programs take descriptions of graphs in a simple text language, and make diagrams in several useful formats such as images and SVG for web pages, Postscript for inclusion in PDF or other documents; or display in an interactive graph browser. (Graphviz also supports GXL, an XML dialect.)
