As an introduction to a series on gun deaths in America, FiveThirtyEight uses a straightforward grid view to show the breakdowns. Each square represents a single gun death, and as you click through, the squares are colored to show various groups. For example, the above represents gun deaths from homicide in blue, about half of which are young men and two-thirds of that subgroup are black.
Sometimes it’s more useful to break the data down to its elements.
