I would like to establish a series of circles that each represent an item in my personal yearly expenses where in each circle's diameter is proportional to the amount of it's particular portion of the total expense. For example a large circle representing the entire expense would have a diameter of 1, a circle representing federal tax might have a diameter of 0.32 if the yearly federal tax was 0.32 of the total yearly expense, a circle representing my credit cards might have a diameter of 0.13 if that was representative of my credit card expenses, and so on.
But as much as I like clickcharts you can only size circles by what looks right to your eye but not by definite relations to other circles
