This visualization examines the relationship between average PISA performance and education expenditure per person across various countries. Although there is a noticeable trend where higher spending tends to be linked with better performance, the relationship is far from linear. Numerous factors, such as the efficiency of expenditure, socioeconomic conditions, and education policies, play a significant role in influencing performance outcomes. This chart prompts a closer analysis of how different countries allocate their educational resources and the subsequent impact on student performance.
