Cost of Living Across Europe by YAAY visualizing complexity

The HICP is the best economic indicator of the real cost of living across Europe. However most people don't know about it.
In a self initiated project we took the challenge of introducing the complex topic to a wider audience and making data comparable on several levels.
We invented a radial deviation diagram, a hybrid of a bar chart and a pie chart. The graph enables a differentiated comparison of price levels between countries, product categories and the deviation from the EU average.
