# Growing circle figure

I need to draw figures related to a computation algorithm which involves circles growing and adjusting themselves in every figure. Later I need to use ellipses instead of circles. Is there any generic approach to drawing this (someway I can just substitute the draw circle command with a draw ellipse command). Figures are as below

and for ellipses

The MWE for the first steps of the packing are as below,(I used a plot digitzser to find the coordinates

• Let me get back to you on that...its not going minimal but I will give it a try :) – Fowaz Ikram Aug 9 '17 at 7:02
• Are the centers moving?(it looks like this) How do they move? – Bobyandbob Aug 9 '17 at 7:40
• Define an x radius and y radius for both, just set them equal for circles. – John Kormylo Aug 9 '17 at 21:54
• One other thing that I can think of is to find the final coordinates and radii of circles in fig (f) and work backwards, but I don't think that going to work for the ellipse case – Fowaz Ikram Aug 9 '17 at 23:42
• If you say circle (1mm and 2mm) you'll get an ellipse, rather than a circle. But I'm not sure how helpful that is. – cfr Aug 9 '17 at 23:55
