In HTML web pages, not only text and images are nowadays displayed, but also complex calculations and application tasks are carried out, since many other ways of displaying data have become possible. I was particularly interested in the topic of graphs, as they offer a variety of possibilities for displaying different data. In addition, well-designed graphs greatly enhance the content of a website and make the website look much more professional. JavaScript itself does not have the possibility to create graphs, but there are various libraries that can be used.
PHP is fundamentally an open source scripting language that is especially suitable for web applications. It is interpreted on the server side and can be easily integrated into the HTML code. Through the server-side integration, the script language enables dynamic websites to be created. In addition, data from user input and databases can be processed.
