Intelligent Graph Visualizer (IGV) allows you to easily create and edit a graph, automatically places the graph on the plane (!!!), search for the minimal path (+coloring vertices), search center (+coloring), search vertices degree, search vertices eccentricity and others.

Features:
1. automatically places the graph
2. search shortest path (+coloring vertices)
3. search center (+coloring vertices)
4. search distance
5. search eccentricity
6. search nearest vertices
7. search radius
8. save to HTML
9. create random graph.
