Data Visualization

Before starting any analysis, it is best to get acquainted with the data at hand and the problem to solve. This part usually consists of an interactive exploration of the dataset, through multivariate graphical plots and statistical measures.

KNIME Analytics Platform offers a few Javascript based nodes for visual investigation, including some classic charts - like the bar chart or the scatter plot – and some more innovative charts – like the sunburst chart or the network graph. All of those views are highly interactive, allowing to change the observation dimension, select and isolate records, edit labels and legend, and more.

All those Javascript based nodes can be assembled together in a wrapped metanode to produce a composite view.  These graphical elements of the composite view can also be combined with controlling elements - such as a slider - to make the whole interactivity experience smoother and faster.

If you also have access to a KNIME server, launching the workflow from the WebPortal displays the same composite view onto a web page.

A reduced version of the workflow shown in this video, and with a smaller data set, can be downloaded from the KNIME EXAMPLES server under 03_Visualization/02_JavaScript/09_DataVisualization_AirlineDataset03_Visualization/02_JavaScript/09_DataVisualization_AirlineDataset^*
