KronoGraph by Cambridge Intelligence is a JavaScript SDK for building interactive timelines. It allows the creation of timeline visualization components that can be embedded in web applications. KronoGraph scales from ten to 100,000 events and supports heatmap views and intelligent data aggregation. Users can combine thousands of timelines into a single visualization and use the lens view to explore individual timelines in context. KronoGraph works with any time-based data, allowing the use of any combination of data sources that contain timestamps or durations. It offers complete control over the appearance and interactions. KronoGraph handles large datasets without demanding huge resources and integrates seamlessly with KeyLines and ReGraph, Cambridge Intelligence's graph visualization SDKs. It includes a detailed API library to simplify application building and features showcase demos for timeline visualization designs. KronoGraph can be hosted anywhere without needing to adapt the current setup and eliminates the need for expensive visualization servers. It works with nearly every datastore, allowing connection to preferred repositories. The SDK includes demos of timeline visualizations, getting started guides, Storybook tutorials with example code, and a live code editing playground. KronoGraph works in major browsers on desktops, tablets, or cell phones and supports JavaScript or React with optional TypeScript definitions. It is suitable for graph databases like Neo4j, other database types, log files, and spreadsheets. KronoGraph visualizes time effectively, enhancing graphs with a time dimension and supports multiple data sources. It includes tutorials, demos, and API documentation, and provides developer support for quick exploration of time-based data. KronoGraph offers flexible control over styles and interactions, allowing the building of investigation tools with the desired look and feel. It supports annotations, labels, glyphs, font icons, tooltips, and highlighting. KronoGraph scales smoothly through time, applies flexible filters, and discovers cliques, groups, and clusters in data. It allows pattern of life analysis by wrapping data to a specific timescale to reveal regular behaviors. KronoGraph includes a nonlinear time scale for managing screen real estate efficiently and focuses on data presentation over time. It supports exporting crime data visualizations with annotations as reports for easy access.
