Hi there!

I've made a simple tool for graph vizualization, that might be helpful in problems solving. The idea was to make something that could be used as easy as just copy-paste from input examples into the tool. It's built on top of Google's Image Charts. Though service is deprecated currently, it works fine. Thanks to Google.

How to use: one of common ways to describe a graph is edges, described on separate lines with their endpoints and possibly some label (weight, cost, etc).

So all you need is to input these lines into the text area and press the button. Try it with these lines:

1 3 10
2 4 11
5 4 10
3 5 12
1 6 10
6 5 12

Is that easy?

You can also:

• comment out some lines with #;
• set checkbox to ignore the first line, that usually contains number of nodes or some other data;
• not show labels;
• plot a directed graph.

Thanks to Edvard for reviewing this.
