How to display reports in the form of graphs on a dynamic html page?

Question

Java

Hello everyone, this is the task. There is a database and a Jetty server. The task is to take data from the database and, on their basis, generate reports in the form of charts and graphs on a dynamic html page. How to implement such a solution? Now I just take the data from the database and roughly insert it into a Javascript script. This is very inconvenient and crooked. Please tell me, maybe there are Java libraries that generate html ready html pages with reports. Or is there some other way to solve the problem? Thanks in advance.
