The Timeline/Graph2D is an interactive visualization chart to visualize data in time. The data items can take place on a single date, or have a start and end date (a range). You can freely move and zoom in the timeline by dragging and scrolling in the Timeline. Items can be created, edited, and deleted in the timeline. The time scale on the axis is adjusted automatically, and supports scales ranging from milliseconds to years.
Install via npm:
$ npm install vis-timeline
A basic example on loading a Timeline is shown below. More examples can be found in the examples directory of the project.

<scripttype="text/javascript"
src="https://unpkg.com/vis-timeline@latest/standalone/umd/vis-timeline-graph2d.min.js"
></script>import{Timeline}from"vis-timeline/standalone";This has no dependencies and therefore is great for things like MWEs but has more issues with interoperability and bundle bloat. For more information see the following (example)[https://visjs.github.io/vis-timeline/examples/timeline/standalone-build.html].
<scripttype="text/javascript"
src="https://unpkg.com/vis-timeline@latest/peer/umd/vis-timeline-graph2d.min.js"
></script>import{Timeline}from"vis-timeline/peer";For this build to work you have to load Vis Data and Moment (including locales except English) packages yourself. The advantage here is that it works well with other packages. For more information see the following (example)[https://visjs.github.io/vis-timeline/examples/timeline/peer-build.html].
<scripttype="text/javascript"
src="https://unpkg.com/vis-timeline@latest/esnext/umd/vis-timeline-graph2d.min.js"
></script>import{Timeline}from"vis-timeline/esnext";This is the same as the peer build but without any bundled dependencies or pollyfills. It's indented to be used with bundlers like Rollup or Webpack which will fetch the dependencies, prevent duplicate dependencies in the bundle, use transpilers to add necessary polyfills etc.
<scripttype="text/javascript"
src="https://unpkg.com/vis-timeline@latest/dist/vis-timeline-graph2d.min.js"
></script>import{Timeline}from"vis-timeline";This is solely kept for backwards compatibility. It is deprecated and will be removed in case of URLs and replaced by the peer build in case of Node.js/bundlers. Don't use this, please.
To build the library from source, clone the project from github
$ git clone git://github.com/visjs/vis-timeline.git
The source code uses the module style of node (require and module.exports) to
organize dependencies. To install all dependencies and build the library,
run npm install in the root of the project.
$ cd vis-timeline
$ npm install
Then, the project can be build running:
$ npm run build
External dependencies such as moment, hammerjs can be excluded in the build by running:
$ npm run build -- -e [comma separated module names]
Example:
$ npm run build -- -e moment,hammerjs
To test the library, install the project dependencies once:
$ npm install
Then run the tests:
$ npm run test
Contributions to the vis.js library are very welcome! We can't do this alone!
