Dear Arie,

There are many tools for visualizing fuzzy clustering results. These tools are the outcome of many researches such as the following:

Abonyi, J., FUZZSAM - visualization of fuzzy clustering results by modified Sammon mapping, IEEE International Conference on Fuzzy Systems, 2004.

Luis Rueda, Yuanquan Zhang, Geometric visualization of clusters obtained from fuzzy clustering algorithms, Pattern Recognition, Volume 39, Issue 8, August 2006, Pages 1415–1429

another is a tool implemented for MATLAB see the following site

http://www.abonyilab.com/software-and-data/fclusttoolbox

The toolbox provides

- 5 different clustering algorithms (2 hard and 3 fuzzy methods);

- 7 different validity measures;

- 3 types of visualization tools for high dimensional data;

Dear friend

In order to see the clustering nodes, you can use plot function in MATLAB.

there are other tools too.

Bets regards

Thank you Dr Awad and Dr Mandal.

Actually I have used Matlab, including plot function and have also used Fclust Toolbox from Abonyi Labs. But, I think those have still limited function and the graph resulted is not quite beautiful enough for popular user. I am trying to find another tools. 

Dear Fernando,

Thank you for your suggestion. I have try Gephi. It has many advanced features. 

There's one new great tool that I'm using recently to build my research figures and presentations, it's very easy to use and it has a gorgeous cientific illustrations database, you should give it a try:
