What is the approximate number of Monopoly City Streets for each price?

I wanted to know how rare is a Monopoly City Street comparing to another according to it's price. So I've made this graphs I hope you find it useful.

In the X axis you have the street price and on the Y axis the number of streets I know of. Please note that it's a just a small set of the whole world.

For streets up to 10 M (click in the image to see a bigger version)

For streets up to 50M (click in the image to see bigger version)

 

Cheers,
