An example from Kaiser Foundation of how excellent visualization and video can very effectively communicate complex legislations is this video that explains the impact of the Affordable Care Act (its portal troubles notwithstanding) on how Americans will purchase health coverage.
The Washington Post has this nice FAQ link on Obamacare. Such graphic videos are powerful instruments to bridge the last mile gaps that often come in the way of effective implementation of important legislations or reform measures. Its greatest impact would be in informing stakeholders, in a cognitively striking manner, about how it would impact them.
Update 1 (2/2/2014)
Good visualization of the possible impact of Obamacare across various US regions.
