Is there any tool to create graphic representation of amino acid composition like in predictprotein.org? I understand it can be easily created in excel, but it will be good if any tool available online. enter image description here

You expect us to register at some site just so we might get an idea of what it is that you actually want to do?

In R:

rand_seq <- "WYEGYQERKMKKNLLGYEQMLRSDFMNTMHPHEDTWICWDYALNQIALNPKTWKVQKSCKASLMPTVDSMYFWYIAHMEMKMQYEWTEWFIHVPYFFDRCFVWYDEFCCQVCMAFLERFRDTNQSSGQLCAWVGYLKNIGYSHYISTILYRYPQEYNIVPTWNIAIMHMQDKVDVECKLNKSMSEHCHHHFPLLAYIDFPLWKPNIYKSPWLMDPFMANLA"

aa_tab <- table(strsplit(rand_seq,""))

pie(aa_tab, col=rainbow(length(aa_tab)), main="Amino Acid Composition")

Unless you didn't mean the pie chart, in which case I can't help, sorry!

simple pie chart

Basically this but with ggplot2, which makes much prettier graphs IMO.
