VOSviewer Online

VOSviewer Online is a tool for network visualization. It is a web-based version of VOSviewer, a popular tool for constructing and visualizing bibliometric networks, such as co-authorship networks, citation networks, and co-occurrence networks.

VOSviewer Online has been developed by Nees Jan van Eck and Ludo Waltman at the Centre for Science and Technology Studies (CWTS) at Leiden University.

The development of VOSviewer Online has benefited from contributions by Olya Stukova and Nikita Rokotyan from Interacta.

The development of VOSviewer Online has been supported financially by Digital Science and Zeta Alpha.

VOSviewer Online has been developed in JavaScript using React, Material-UI, D3, and a few other open source libraries.

Usage

VOSviewer Online is hosted at https://app.vosviewer.com. Using VOSviewer Online, visualizations of bibliometric networks created by VOSviewer can be explored interactively in a web browser. To open a visualization, use the Open button at the top right of your browser window. See the documentation for an explanation of the user interface of VOSviewer Online, the interpretation of a visualization, and the file types supported by VOSviewer Online.

VOSviewer Online can also be used to share interactive visualizations by embedding these visualizations in webpages and online platforms.

Embedding VOSviewer Online in a webpage using an inline frame

VOSviewer Online can be embedded in a webpage using an inline frame (<iframe> HTML element), as illustrated by the following HTML code snippet:

<iframe
  allowfullscreen="true"
  src="https://app.vosviewer.com/?json=https://app.vosviewer.com/data/QSS_SM_2020-2021_co-authorship_network.json&simple_ui=true"
  width="100%"
  height="75%"
  style="border: 1px solid #ddd; max-width: 1200px; min-height: 500px"
>
</iframe>

For more information, see the documentation on sharing a visualization.

Integrating VOSviewer Online in a React application

VOSviewer Online can be integrated in a React application using the VOSviewer Online React component package published on npm.

Run

npm install vosviewer-online

The following code snippet illustrates the use of the VOSviewer Online React component:

import { VOSviewerOnline } from 'vosviewer-online'

<VOSviewerOnline data={{ ... }} parameters={{ ... }} />

The data and parameters props are optional. The data prop can be used to provide network data to the VOSviewer Online React component. The data must be in the VOSviewer JSON format.
