graph
What It Means
A graph is a way to show how different things are connected to each other, like a network diagram with dots (nodes) and lines (edges) between them. In AI and data systems, graphs represent relationships between data points - whether that's customers connected to products they bought, employees reporting to managers, or web pages linking to other pages. Think of it as a visual map that shows not just individual pieces of information, but how they relate to and influence each other.
Why Chief AI Officers Care
Graphs are fundamental to many AI applications that drive business value, including recommendation engines, fraud detection systems, and knowledge management platforms that help organizations understand complex relationships in their data. Graph-based AI can reveal hidden patterns and connections that traditional analysis misses, leading to better customer insights, more accurate risk assessments, and improved decision-making. However, graph systems require specialized infrastructure and expertise, making them a significant technical and budget consideration for AI initiatives.
Real-World Example
Netflix uses graph technology to power its recommendation system - they create a massive graph where users, movies, genres, actors, and viewing behaviors are all connected nodes, allowing their AI to suggest 'Stranger Things' to you based on complex relationships like 'users who watched sci-fi shows starring young actors and had similar viewing patterns to yours also enjoyed this series.' This graph-based approach generates billions in revenue through improved user engagement and retention.
Common Confusion
People often confuse graphs with simple charts or visualizations, but in AI contexts, graphs are actually sophisticated data structures that store and process relationships between entities. The confusion comes from the word 'graph' meaning both a basic bar chart and these complex network structures that power modern AI systems.

"Diagram that represents the variation of a variable in comparison with that of one or more other variables. Diagram or other representation consisting of a finite set of nodes and internode connections called edges or arcs."Source: IEEE_Soft_Vocab
"A graph (sometimes called an undirected graph to distinguish it from a directed graph, or a simple graph to distinguish it from a multigraph) is a pair G = (V, E), where V is a set whose elements are called vertices (singular: vertex), and E is a set of paired vertices, whose elements are called edges (sometimes links or lines)."Source: wikipedia_graph_2023
