Visualization Basics

Introduction

Data visualization is the graphical representation of information and data. In Grafana, visualizations are the building blocks of dashboards that transform your raw data into meaningful, actionable insights. This guide introduces you to visualization fundamentals in Grafana and helps you understand how to choose the right visualization type for your data.

Why Visualizations Matter

Raw data can be difficult to analyze. Visualizations help by:

• Making patterns and trends immediately visible
• Enabling quick comparison between different metrics
• Highlighting outliers and anomalies
• Communicating complex information in an accessible format
• Supporting data-driven decision making
