My Top 13 JavaScript Diagram Libraries

Nowadays, the amount of data grows exponentially, and the more information we see, the more painstaking and time-consuming it gets to analyze it. With the advent of big data, the business world faced the necessity to shift from traditional Excel spreadsheets to more effective ways of data visualization – colorful and interactive diagrams, charts, dashboards, maps. Thanks to modern data visualization tools, people can spend less time and effort on grasping difficult concepts or identifying new patterns, thus making a significant contribution to more effective decision making. In most cases, developers resort to using JavaScript, as it is the most universal and easy-to-use technology for data visualization. Currently, there is a large number of JS diagram libraries available on the software market and each one of them has its own pros and cons. In this article, I will try to help developers who are still in quest of a proper diagram library for their projects by reviewing 13 remarkable solutions (presented in alphabetical order). 1) Basic Primitives Diagram is a JavaScript library providing different diagramming components that are utilized for dependencies visualization and analysis. Basic Primitives ensures proper display of complex diagrams within a single screen space without any negative impact on the diagram usability. The auto-layout feature offers a lot of functional capabilities for the overview, editing, and navigation through diagrams. When any changes are introduced to the diagram, special API elements (annotations) are used to show the process of diagram shifting from one state to another. Basic Primitives Diagram Written in pure JS without dependency on 3d party libraries, this library supports modern and mobile browsers as well as graphics rendering in VML, SVG, and Canvas modes. One of the most remarkable features of this library is that independently of the license being used (free or commercial), you can download the source code and introduce any kind of changes in it. Thanks to a full API, developers can add, change, or remove any elements of the diagram or their properties, and the library will render only the elements modified via the API, thereby providing fast rendering and high performance. org chart, family tree & inheritance chart, multi-parent hierarchical chart, dependencies visualization, PERT diagram, directed acyclic graph (DAG) visualization, business ownership diagram Types of supported diagrams: AngularJS, jQuery, ReactJS Integration with JS frameworks: Availability of Diagram Editors: organizational chart editor not found Diagram export formats: non-commercial (free) 3.0 License; commercial licenses from 385$ to 2,145$ License and price: 2) DHTMLX Diagram is a handy JavaScript diagramming library that allows you to add well-structured and interactive diagrams and org charts to your web app. Thanks to its lightweight, the library ensures fast rendering and high performance. The DHTMLX Diagram component makes it possible to build different types of diagrams, including mixed diagrams (diagram + org chart) with the help of a predefined set of shapes and connectors, and custom shapes. All shapes can be complemented with textual data, icons, and images. Zooming and scrolling features ensure more convenient and effective working with large diagrams. DHTMLX Diagram Interestingly, you won’t need much time to build even the most complex diagram with a great number of shapes, as this library provides an advanced auto-layout algorithm. This powerful feature helps to turn chaotically placed shapes into a well-structured diagram in just a few clicks. This library is compatible with any server-side technology and supports all popular browsers. But the most remarkable thing about DHTMLX Diagram is the availability of two live editors (one for org charts and one for other types of diagrams). These editors enable you to enrich standard diagrams with custom shapes and change their appearance on the fly using highly-customizable side panels. The possibility to perform standard actions on several shapes (select, move, copy, etc.) at the same time and apply the smart layout algorithm helps to create diagrams of any scale much faster.
