Cal Heatmap
cal-heatmap is a JavaScript visualization library used to render time-series data as a grid of colored cells. It functions as a customizable calendar component that maps data density and frequency over temporal intervals ranging from minutes to years.
The library provides built-in support for localized temporal displays, allowing for the adjustment of regional date formats, timezones, and locale-specific week starts. It utilizes a plugin system for both the calendar layout and heatmap charts to extend behaviors and visual styles.
The system manages data visualization through SVG-based grid rendering and includes capabilities for calendar date navigation and layout configuration. It also supports data-driven color mapping to translate numerical values into visual density patterns.
Features
- Activity Heatmaps - Renders time-series data as a grid of colored cells to highlight activity patterns over time.
- Time-Series Visualizers - Represents data density over time using a grid of colored cells to identify patterns and trends.
- Numeric and Date Formatting - Adapts date and time information to different languages, timezones, and regional calendar formats.
- Regional Conversions - Adjusts language and timezone settings to ensure dates and week starts match regional expectations.
- SVG-Based Vector Rendering - Generates a scalable vector graphics layout to represent temporal data as a coordinate-based grid.
- Locale-Based Date Normalization - Processes UTC timestamps into local date representations using locale settings to ensure accurate alignment.
- Calendar Visualization Components - Provides a customizable UI component for rendering time-based data records within a grid interface.
- Locale Displays - Adjusts date formatting and layouts based on specific locales, timezones, and reading directions.
- Localized Temporal Displays - Offers built-in support for regional date formats, timezones, and locale-specific week starts.
- Calendar Layout Plugins - Provides a plugin system for adding new behaviors and customizing layout options for the calendar.
- Chart Visualization Plugins - Implements a plugin system for heatmaps to integrate custom behaviors and visual enhancements.
- Density-Based Color Gradients - Implements data-driven color mapping to translate numerical values into visual density patterns.
- Extensible Component Architectures - Separates calendar logic from chart visualization to allow independent configuration of styles and scales.
- Hook-Based Plugin Systems - Provides a standardized hook and registry system for external modules to modify internal behaviors.
- General Activity Dashboards - Enables the creation of visual interfaces that track user engagement or system events over long periods.
- Layout Customization - Allows customization of time intervals and navigation animations to fit specific temporal data scales.
- Temporal Navigation Interfaces - Provides dynamic browsing through different time periods to view historical data.
