These graphs provide a detailed breakdown of Datafolha's latest poll, showing the drastic drop in Dilma's approval ratings. The first graph traces her approval over time, beginning with March 2011. She reached a peak in March 2013, just a few months ago, making her rapid decline even more dramatic.
The next set of graphs shows her approval ratings by region, followed by graphs that show approval by income, education, gender, and age.
There's lots of interesting data here, so feel free to geek out.
Note: In order to make the graph large enough to read, you have a couple of options:
1. Click on the graph, then right click and select "open in another window" in Safari ("open image in new tab" in Chrome). That will allow you to enlarge it enough to be legible in your browser.
2. Download the PDF to your computer (right click on it and select "save image as"), then open it and enlarge it.
