      <p>The graph shows the trend of Japanese population growth since WW2. As the reader moves the slider towards present days. It shows the population growth is moving into negative territory in most areas, except Tokyo and Osaka region. Also it shows a huge growth in some regions right after the war, and the urbanization of Tokyo since the end of war. For more information, please refer to README.md file.<p>
