What language to create interactive data visualizations? : web_design

Hello. I want to make interactive data visualizations. What I mean, for example, is I want the user to be able to hover over a data point on a coordinate plane and then information about that data point will appear next to it. Or like how in this example on FiveThirtyEight the user can use their cursor to see the approval rating over time. This guy made an example of basically exactly what I’m looking to do. Here’s another more interactive example.
I know how to use WordPress, and how to get around in HTML, CSS, and a tiny bit of JS. I want to know what language one needs to learn to do stuff like explained above though. Thank you!
