Data:
TradingEconomics debt to GDP ratios for Europe.
Tools:
Python, using Matplotlib and Basemap.
I tried an approach where I incorporate a map with color gradients to get a quick overview and find the most interesting info (e.g. your own country or the worst/best country), numbers on the map for details at a glance and the bar chart to more easily get an idea of the ranking and distribution of the ratios among the countries. Higher information density, but hopefully not too much.
