Looking for suggestions on what to use to make a webpage that contains a dynamically updating image

I am extremely new to web development and I am looking into making a webpage that holds an image that can be quickly updated dynamically. I want to have a server that processes/holds the updating image, and it will continuously send to the client this new image (via a byte array that can be converted to an image) for it to update on the webpage.

For example, a maritime navigation radar unit will have the radar image constantly updating every few seconds with a new image for every new sweep of data. I want to be able to manipulate each pixel on the radar bitmap on the client side.

I have looked into ".ASP .NET Core web apps" and "Blazor Webassembly" projects but they just don't seem to do what I need; but it could just be my limited knowledge with web development. I am comfortable with C++/C#. Any recommendations of a coding language/platform I can look into for doing this?

Thanks.
