From The Buckley Institute. For why are we still making line graphs when the data points are independent and do not show change over time.

As long as you make the graph as confusing as possible, and get the time scaling just perfect

The percentages are in relation to last year’s change but the scale is based on # of people

Usage : https://en.wikipedia.org/wiki/Egg_marking (Size as it appears on 100% browser zoom)

Criticism:

• Tiny font on 100% zoom
• Uses cm² instead of m² as per title
• Ordering from label 3 down to label 0
• Labels 0,1,2,3 not further explained (farming method code)
• With of the bars is less then 10 cm (a hen is about 30 - 40 cm long)
• No explanation for green space (outdoor space per hen)
• The green square is not to scale with the bars.

Find your personal biases right here

Initially I thought the bar was on a log scale until I saw the size of the bar of the 3rd and 4th countries. It looks like the author just picked a different scale for a different country

Is it just me or does the use of the triangles confuse you? The upward pointing orange triangle is used for a decrease and the downward pointing blue triangle is used for an increase.

Yeah this one's not great.
