This is the visualization based on the survey conducted by the government about American Time Use. It shows how people spend their days means exactly at what time they work.
I found this interesting mainly because of the use of interactivity. Also, the distribution of work schedule is rightly displayed by histogram. Using two filters user can analyze how much is the difference in work schedules for different occupations.It seems overcrowded at first sight but use of highlighters and shading have made it easy to perceive.
We can see most of these occupations fall under conventional work shift 9 a.m.- 5 p.m. But emergency services (police officers, fire fighters) have higher share of work till midnight.
Another interesting thing is we can see who takes lunch break most seriously and who are workaholic. And obviously, this is peak time for chefs and food services.
I think this graph can be made more appealing if it shows comparison between countries as well. That will be interesting to know cultural differences in work time. Another limitation of this data is for white collar work, the line between life and work can be blurred. For example, lunch or dinner with client can be considered as part of work. This throw a wrench into how work hours are measured overall.
