How to reconstruct visualization through a .lp file

[pouralise]

I have a task to ask
I have an already builded Visualization, but I dont want to show it in visualization page but to reconstruct it in a .lp file. The main purpose is I dont want to show this visualization to any one even if they have admin permission, but I still want to access that visualization when I need through a .lp file with a secret authentication.  Example It will show the visualization when I connect to 

http://192.168.0.10/public/vis.lp?authentication=abc



I think there will be some steps to do like this:
Step 1: Build a visualization (already done)
Step 2: Store parameter of the visualization to a file such as data.txt (not sure what I need to store, maybe by db:update or F12 from webbrowser)
Step 3: Delete the visualization (but still keep the resource like image, font...)
Step 4: Creat a vis.lp file that will reconstruct the visualization from the data.txt file. It will have code like that

Code:

<?
require('apps')
data = ngx.var.request_uri

if data == 'authentication information' then
  data = io.readfile('data.txt')
  -- code to use data to reconstruct visualization here
end

Can you help me to find a way to do this, maybe a simple example is great. Thank you very much

Open visualization, open "view source" in your browser (CTRL+U), copy/paste the code into your .lp page.
