Bubble Chart Matrix Visualisation??

Hi everyone,

I dont know about you but recently a lot of clients want to see data in a bubble chart martix. I thought this would be sort of standard but it turned out harder than expected. 

I tried to set up scatter chart but the size of the bubbles makes differentiation impossible. One bubble with a value of 1000 is just a little bit larger than a bubble with a value of 15. 

How do you solve issues like that for a client? Is there an alternative? I have searched the marketplace - nothing so far.

It should be like thatMine looks like this here. The relations between the bubbles doesnt make sense. One bubble is a little smaller than another but the values differ greatly. Eg is the darker blue button maybe a 1000 and the lighter blue maybe 15.
