From the Twitter bio:
Meie Raha visualizes Estonian budget so that it would be understandable to everyone.:
From the website’s about page:
What is Meie Raha?
Annual state budget is a complicated thing. The official Budget Bill is made up of long tables that do little to explain how the taxpayers’ money is spent. Meie Raha — Estonian for “Our Money” — shows major income and expenditure articles at a glance, structured by government functions.
The visualization shows two sides of the equation — income (mostly taxes) and expenditure by category. The size of bubbles is proportional to the size of budget items. This simple visual helps to compare the sums. One can click on a bubble to see cost articles within each budget heading. Or try dragging the outline of a bubble to see how manipulating different sums results in the balance of the budget. Ideally, every budget needs to be balanced, so the changes you make on the spending sides should be balanced on the income side!
