dygraphs is a fast, flexible open-source JavaScript charting library for rendering interactive, zoomable time series charts using the HTML canvas tag. It handles dense datasets with millions of points and works in all modern browsers without any server-side dependencies.

Use cases

• plot time series data in the browser
• interactive zoomable charts for dense datasets
• visualize sensor or monitoring data over time
• add pan and zoom charts to a web dashboard
• display confidence intervals or error bands on charts
• chart millions of data points client-side

When to choose

• you need interactive time series charts with zoom, pan, and mouseover out of the box
• your datasets are large (millions of points) and must render client-side
• you want a lightweight dependency-free canvas charting library
• you need error bands or adjustable rolling averages

When to avoid

• you need chart types beyond time series (pie, bar, scatter-heavy dashboards)
• you want a React/Vue component-based charting ecosystem
• you need server-side or SVG-based rendering
• you require extensive theming or modern design-system integration
