Firstly, I want to thank you to take your time to read and help me.
This question is related to my previous question, however, I want to place separately, due that I think it could be done by different means.
Previous question if you want to read it (not necessary): Presenting a yearly data from a CVS/XLSX on a WEB PAGE (html) and simulate a Real-Time
I am not familiar with web developing (but I have to); I know basic Python and SQL.
Objective: The object (imagine a circle or rectangle in a web page HTML) has to present or show (in the middle) a value and change his color according to this value.
This object has to read this value every 15 minutes from a CVS or Excel file. (to simulate a real-time).
This reading is a number from 1 to 100.
The background of this object has to change accordingly with this number. For example. If the value is 0, the background has to be red; if the value is 100, the background is green. And, in between the color could be degraded from red to green.
I really appreciate your help guys, I am in a huge hurry to show make this and I do not have any clue for where to start.
I have written some basics HTML codes for basic web pages. But nothing related to PHP, JS, CSS etc. Also, it could be a third party application.
