Sinatra VS matplotlib

Compared to Ruby on Rails, a full-stack web framework, Sinatra is a very lean micro-framework originally developed by Blake Mizerany to help Ruby developers build applications with "minimal effort".

Let's say I have the simplest single-file Sinatra app. The hello world on their homepage will do. I want to run it under Apache with Phusion Passenger, AKA mod_rails.

Sinatra is the oldest competitor of Rails. Although it's not that popular anymore, it's still used in some simple and performance focused services.

Sinatra is fine as long as you have a small number of routes, because its router is O(n): https://github.com/sinatra/sinatra/blob/ac5404dbd897a4b3c5b3921d2f89fecd3b540ed3/lib/sinatra/base.rb#L1008-L1010

Tool: Matplotlib Pyplot

The issue was described here: https://github.com/matplotlib/matplotlib/issues/8409, but the "solution" was just "this is fixed" which was not helpful to me.

Matplotlib: Matplotlib is a 2D plotting library that allows you to create visualizations of your data. It's a powerful tool for data analysis, but the syntax can be complex and the customization options can be overwhelming. GitHub - https://github.com/matplotlib/matplotlib

A quick google shows: this history.txt:

Let's take a small subset i.e 20 data points of our prediction and compare it with actual output using matplotlib library

I will think more about what I want to say next, but for now, I would like to say that I need the super-particles and PIC methods as I think that is the way forward for me. Are there ways to implement these methods in matplotlib, Visit or Paraview? Do I take existing code and import it into those programs to visualize it? Or can I directly program/simulate something in those visualizion tools without needing to import any code?
