Based on the information provided, I don’t have access to the specific chart or data. However, you can determine which country had the greatest annual change in GDP per capita from 2010-2015 by looking for the country with the highest growth rate in GDP per capita during that period.
If you have the specific values for GDP per capita for each country from 2010 to 2015, you can calculate the annual change by finding the difference between the GDP per capita in 2015 and 2010, then dividing by the number of years (5). The country with the highest value from this calculation would be the answer to your question.
If you can share the data from the chart, I could help determine the correct response.
