For this practice, I will use Public Tableau to visualize a dataset. I decided to work with a dataset that captured global shark attacks. To keep things simple, I will be looking at United States shark attacks and will strictly look at states that border the Atlantic Ocean, Pacific Ocean, and the Gulf of Mexico.
For some odd reason, there was a strange number of shark attacks taking place in landlocked states such as Missouri and New Mexico but these attacks were disturbingly unnatural and were often provoked by an individual jumping into a shark tank at a aquarium.
Anyway, the goal of this visualization is to determine the average age of shark attack victims by state.
Below, is a link to the visualization's main page:
Average Age of Shark Attack Victims
By looking at the color scale of the map, one can see that the darker the color, the older the shark attack victim tends to be. Thus, in states like Massachusetts, Connecticut, and Alabama, the victims tend to be older but technically middle age.
Massachusetts - Average Victim Age: 41
Connecticut - Average Victim Age: 38
Alabama - Average Victim Age: 34
As for states with the youngest victim age, Texas had the youngest age with it being 18 and other states in that similar shade were clustered around that age as well.
Texas:
Georgia:
Virginia:
As for graphic elements that would make the map more communicative, I would think that adding location points of where the victims were attacked to the visualization would make it much more interesting to look at. Additionally, I would like to make the legend I generated in Tableau play a bigger role in the visualization as a whole. Currently, it is pushed off to the side and small. I would prefer that the legend on the map so that viewers do not have to look around for it.
