I just read the follwing here https://en.wikipedia.org/wiki/Adobe_Flash_Player:
As the support ends I assume that more and more user will not install or deinstall flash. Then the generated graph will become useless. Is there an planned alternative (HTML5?) or is there something else available?In July 2017, Adobe announced that it will end support for Flash Player on December 31, 2020, and continued to encourage the use of open HTML5 standards in place of Flash.
