The first diagram is completely false.
This is like telling a kid they have 11 fingers.
You point on one hand, 10, 9, 8, 7, 6 and then say plus 5 is 11 !!!
The circles should be drawn where the surface is proportional to the market cap
number and not the radius.
 
If you know the area of a circle (in this case the Market cap), the radius can be
 found using the formula r=square root of (Area/Pi)
 
If you are going to use the radius method to draw the circles here are the correct numbers.
It is these I used to draw the correct graphic.
