A makeover of a Marimekko chart for a similar message. A layout with comfortable read/scan and comparison of the most relevant encoded variable: the percentage. One might argue that lengths are easier to compare. True, yet a Marimekko layout hardly gives comparable sizes.

A graphical alternative which emphasizes the gaps and avoids overlapping.

Triggered by the existing circle shaped flags, I couldn't resist to try a colorful density dot plot. The arrangement follows the distribution shape. If we admit a slight error displacement, we can reduce overlapping (2nd image). #makeovermonday

In the article there are mentioned the expectation gaps as RELATIVE value (eg. 2.2x for US, also displayed in the table), while the gray bars are used to graphically encode the ABSOLUTE values. Encoding the two distributions next to a sorted by gap table might be easier to read.

Having a bit of fun. As mentioned yesterday, RELATIVE gaps are not properly encoded by a dumbbell chart, which basically encodes the ABSOLUTE gaps. BTW, a bar chart to visually compare relative gaps (comparing ratio of ratios)? A dot chart is a more appropriate option.

A crystal clear takeaway combining two great dataviz techniques: reading the signal (instead of the noise) and using area for highlighting two line charts difference.

Looking into the evolution of the relationship between two variables. Using the normalized covariance parts to encode the systematic relationship (how the change of one is reflected in the change of the other). Using different smoothing degrees for interpretation.
