Which country do you like the most?

The caption below the graph in the image states that is how you should interpret the results in some places:

The map compares the popularity of the U.S. and China in each country based on their net perception score (measured as the difference between the share of respondents with a positive perception minus those with a negative perception of each country.) The country with the higher net score is relatively more popular, or less unpopular.

Xi is only one with more positives than negatives.
