Mandelbrot in Mojo with Python plots

Not only Mojo is great for writing high-performance code, but it also allows us to leverage huge Python ecosystem of libraries and tools. With seamless Python interoperability, Mojo can use Python for what it's good at, especially GUIs, without sacrificing performance in critical code. Let's take the classic Mandelbrot set algorithm and implement it in Mojo.

We'll introduce a Complex type and use it in our implementation.

Mandelbrot in python

Hello, Rust community!

My name is Hadrien and I am a software performance engineer in a particle physics lab. My daily job is to figure out ways to make scientific software use hardware more efficiently without sacrificing its correctness, primarily by adapting old-ish codebases to the changes that occured in the software and computing landscape since the days where they were designed:

CPU clock rates and instruction-level parallelism stopped going up, so optimizing code is now more important.
Multi-core CPUs went from an exotic niche to a cheap commodity, so parallelism is not optional anymore.
Core counts grow faster than RAM prices go down, so multi-processing is not enough anymore.
SIMD vectors become wider and wider, so vectorization is not a gimmick anymore.

	# Run this script from the root directory of the mpv repo.

	# if anything fails, gtfo

	# This gist is a step by step instructions to build and install OpenCV from source on ubuntu 18.04 LTS
	# note: The easy and quick way to install is
	# sudo pip3 install opencv-python
	# sudo pip3 install opencv-contrib-python
	# But this easy pypi installation can’t open video files on GNU/Linux distribution or on mac OS X system.
	# And on some system opencv binaries provided packages are not compiled.
	# Therefor we have no way rather than build it from source.

	Step 1: Add Nodejs PPA
	Node.js is available in two versions, first is current (most recent version) and another is LTS. Select which version you need to install on the system. Then use one of following commands to install PPA on your system. Node.js officially provides these PPA’s.
	Use Current Release: At te last update of this tutorial, Node.js 8.0 is the current Node.js release available.

	Command:
	$ sudo apt-get install python-software-properties
	$ curl -sL https://deb.nodesource.com/setup_8.x \| sudo -E bash -

	Use LTS Release : At te last update of this tutorial, Node.js 6.11 is the LTS release available.
	Command:
