This week we chose data about police violence. It’s not a happy dataset but it is a very important one. The organisation Mapping Police Violence has data on every shooting in the US in 2015. The original article and charts can be found here.
Things I liked about the original charts:
- I found the formatting simple and striking
- I liked the simple approach to showing the data.
- They callout the key departments they are telling the story about (departments which shot only black people last year)
Things I didn’t like:
- The bar chart has vertical labels – I don’t like turning my head!
- They split the number of deaths and the rate of deaths into 2 separate charts.
- The warning symbol for departments that killed only black people didn’t appeal to me as a clean visual indicator.
For my makeover, I wanted to stay true to their intention: a clean list, showing just the numbers. There’s power in these numbers which don’t need elaboration. I turned the rate of killings into a bar, as that’s simply the best way to show magnitude of a measure.
I added the number of deaths as a sized circle at the left of the bar. I toyed with just adding the number, but it was hard to identify what that number meant. I also put the labels inside the circle. I wanted to imply the magnitude of what these big numbers mean: people killed.
I took the same colour scheme as Mapping Police Violence for my own chart.
In the original, the commentary to the chart is placed on the right hand side of the chart. Since I chose to use a sorted bar chart, I have lots of white space on the middle and lower right of the chart. I added the commentary there in order to make good use of this blank space.
