Draw lines between several points with known coordinates

My task: to connect points with lines using known coordinates.

What I have already done: using the doctr library, I find the coordinates of the words I am interested in on a pdf file. (My python code is not important for this question, below I will show what data I get from a specific file)

For example, there is a pdf file in which I am looking for the word "INVOICE"

enter image description here

After doctr has run, I get the following data

((0.09370404411764705, 0.0439453125), (0.33140099789915967, 0.09765625));

((0.5925912552521009, 0.1796875), (0.6575433298319328, 0.1953125));

((0.5925912552521009, 0.2041015625), (0.6575433298319328, 0.21875));

My question: how can I draw lines between these three points? To get a figure at the output. For a better understanding of the situation for you: the figure on this file will be like a template for me. I receive a large number of documents, and in order not to look through everything, I will check whether this figure is on the received document, and look through only the necessary document.

You can use PyMuPDF Library. The following code snippet will help you.

import fitz  # PyMuPDF
doc = fitz.open("Document_Name_Original.pdf")
page = doc[pno]  # page number
p1 = fitz.Point(x_1, y_1)  # First point
p2 = fitz.Point(x_2, y_2)  # Second point
p3 = fitz.Point(x_3, y_3)  # Third point
page.draw_line(p1, p2, color=fitz.pdfcolor["red"], width=2)
page.draw_line(p2, p3, color=fitz.pdfcolor["red"], width=2)
page.draw_line(p3, p1, color=fitz.pdfcolor["red"], width=2)
doc.save("Document_Name_Modified.pdf")

Through this library, you can modify, add graph and add any plotting. If you want to know detail, this link 1 and link 2 help you for guide drawing on PDF document.
