How The Treasury Cuts The Budget (in retrospect)

This is my scatterplot excercise where I use two circles for each item to show the difference in radius between the 100% of the budgets and the percentage left in them at the end of the year.

<h1>How The Treasury Cuts The Budget (in retrospect)</h1>

<p>This scatterplot shows the greatest cuts made to Israeli budgets through the budget year after being approved in parliament since 2013. All these budgets saw more than 100,000,000₪ cuts with some losing as much as 2/3 of their originally allocated funding even though they were not officially designated as reserve items. Some of them might actually be hidden reserves. Source: <a href="https://data.obudget.org/queries/53/source">oBudget.org</a>, 2015</p>
