LEARNING PATHS
Navigate data science as a knowledge graph
Explore SQL, Python, visualization, machine learning, deep learning, and AI systems as connected lessons.
INTERACTIVE KNOWLEDGE GRAPH
Choose your next lesson visually
Click a node to inspect prerequisites, next lessons, learning time, and Colab practice links. Mark completed lessons to build your personal map.
HOW TO SCALE
Add new lessons without redesigning the site
Each lesson is a data object with a domain, level, prerequisites, next lessons, and optional Colab URL. Add new objects to grow the graph.
