Description: Relatively easy access is provided to 2023 version of the Maddison 
      project data downloaded 2025-08-28. This project collates all the 
      credible data on population and GDP for 169 countries, with some dating 
      back to the year 1 of the current era. One function makes it easy to find 
      the leaders for each year, allowing users to delete countries like OPEC 
      with narrow economies to focus on technology leaders. Another function 
      makes it easy to plot data for only selected countries or years. Another 
      function makes it relatively easy to obtain references to the original 
      sources, which must be cited per the copyright rules of the Maddison 
      Project for different uses of their data.
