Bar charts

The following visualizations were first drafted in Tableau and later finalized in D3. This link shows a bar chart of the total number of attacks by target type with each bar subdivided by the used weapon type. In the updated version an interactive tooltip is added that shows for each bar the exact number of attacks. The visualization shows that the number of attacks is highest for the target type private citizen and property, followed by military and police. It also shows that the number of attacks is highest for the weapon type explosives, followed by firearms.

These conclusions are validated by rotating the variables of this bar chart, such that the total number of attacks is measured by weapon type with each bar subdivided by target type, see this link.
