Here is a Viz (visualisation) I created while self-teaching Tableau, a widespread analytics software with amazing potential and capabilities. It explores the statistics of fatalities in Australia. You can filter data by road user (drivers, passengers, cyclists etc) and by year, with the filters on the right side.

It's not the happiest topic, i know, but it is free available data and offers a couple of important higlights:

• the first two histograms can give an overall insight:
  • over the years there are less fatalities even if the Australian population is actually increasing: it seems like either we are getting better at driving, or the government is putting in place some effective measures for preventing fatalities;
  • there are many more males dying on the streets than females (are there actually more males on the streets?!?)
  • some states like NSW and VIC are doing better with time; others like WA seem to have little improvement over time;
• the third graph, distribution of fatalities VS age, actually gave me a chill on my spine:
  • some kids less than 16 yo are involved in accidents while they are driving!  
  • young inexperienced 16-21 years old are actually the highest fatalities
• in the forth graph you can see when fatalities happen:
  • 16-21 years old happen to die much more often during party nights according to the 4th graph
  • cyclists die more on the way to the office and back rather than on the weekend 
• the fifth graph gives an idea of where the accidents happen:
  • the highest fatalities are on highways (100km/h)
  • many happen in roads with 60 and 80 km/h (which are actually the most common speed limits)
• the separation by days of the week seems to suggest that somehow we are more careful at the beginning of the week and we slowly get less alert during the week. It is hard not to associate the high fatalities over the weekend with the plague of drinking&driving.

Do you see any other patterns? I would be very glad to have your ideas or to know what you see from these data!
