D3 Examples - Responding to Resize-Perception of corruption by institution, global aggregate, 2013

Data Source
The Global Corruption Barometer, produced by Transparency International, asks individuals across countries about whether they perceive specific institutions to be corrupt. The following chart presents, by institution, the global aggregate figures. The numbers correspond to the percentage of survey respondents that think each institution is “corrupt or extremely corrupt” in their home country.
