+ One of the starting points of the visualizations of vis.js is that they can deal with dynamic data, and allow manipulation of the data. To enable this, vis.js includes a flexible key/value based DataSet and DataView to handle unstructured JSON data.
+
+ By providing a DataSet with data to the visualizations, they can subscribe on changes in the DataSet and automatically reflect the changes in their view. Changes in the data can be caused by a server pushing updates to a client, or by other interactive components in the web application. Vice versa, data can be manipulated in one of the visualizations. For example a REST-client can listen for changes and automatically write changes to the server. Or changes can be propagated to other parts of the web application.
+
+ A DataSet can be used to store JSON objects by id. Objects can be added, updated and removed from the DatSet, and one can subscribe to changes in the DataSet.
+ The data in the DataSet can be filtered and ordered, and fields (like
+ dates) can be converted to a specific type. Data can be normalized when
+ appending it to the DataSet as well.
+
+ Go to the documentation of DataSet +
+ +
+ A DataView offers a filtered and/or formatted view on a DataSet.
+ One can subscribe to changes in a DataView, and easily get filtered or
+ formatted data without having to specify filters and field types all
+ the time.
