I’m building a web based HMI (user interface) that shows some SVG objects that change their state according to data received from a python app. I simply need to change the color of the SVG objects if a function is ran in the backend.
For example:

<path style="fill:#5d5d5d;fill-opacity:1;stroke-width:0.264583" d="m 34.350404,74.999997 h 2.5" id="path13" />

In my python app, there would be a function like “update_path(pathID, color)” that changes the fill color of the path, something like update_path(path13, “#ffffff”).

I’m not sure how to approach this, I’ve been looking at flask and fastapi but I have no web development experience and it’s all a bit confusing. Do I use javascript and exchange data with the backend or I can simply update the web page directly? The flux of data is pretty high, there are multiple objects that update quite frequently.
