Graphs Made Simple: From Social Networks to AI – Here’s How They Work

See how to use graphs in Python to model real-world connections like social networks, maps, and AI systems with a code example.

We’ve all been on trips where we want to try to cram in a bunch of different cities. We have to try to figure out which ones we can get to, how they’re connected, and the fastest way between them.

We’ve all tried to solve this puzzle, right? But really, this is actually a graph problem.

Graphs are something we use in computer science to show how things are connected. They’re incredibly useful and show up everywhere—from social media and maps, to Netflix recommendations and airline routes.

They help break down and solve problems by showing the relationships between different things, these things we will call Nodes.

Each week, I dive deep into Python and beyond, breaking it down into bite-sized pieces. While everyone else gets just a taste, my premium readers get the whole feast! Don't miss out on the full experience – join me today!

In this article, you’ll learn what graphs are, why they matter, how they work, and how to build them using Python.

I’ll keep things real simple with some examples, clear comparisons, and easy-to-follow Python code so everything makes sense as you go.
