Words to be shown on the index page with a size,position and color depending on how many times the words were typed by the Visitors

I have a search box whenever user type any word and press enter that word save in database. I have queries through which i can get the info that how many times one word is entered by visitor. But i need a layout like this with a size,position and color depending on how many times the words were typed by the Visitors

1. Letters sizes-based on the searches-the smallest letters are for searches that are not popular;the largest letters are for the most popular words
2. Letters colors-random shades of grey
3. Words cloud-the words,which are not popular are on the top of the cloud;the popular words are at the botom

This should be the layout

Can anyone help?
