This example visualizes the 2023 Legatum Prosperity Index dataset, mapping geographical distributions of average prosperity and personal freedom scores while exploring correlations between variables like education, health, and living conditions. The code loads CSV data and converts string values to numbers for analysis. It displays the first data entry as a formatted JSON preview using a template literal, providing an initial glimpse into the dataset structure. The implementation uses plain JavaScript DOM manipulation to render the output, with data sourced from a Kaggle-hosted CSV file.
