Elasticsearch Tag Cloud

Tag Cloud represents text in an attractive form, mainly keywords and metadata. They are aligned at different angles and represented in different colors and font sizes. It helps to identify the most prominent terms in the data. The prominence can be determined by one or more factors (such as the frequency of terms, the uniqueness of tags, or the weight attached to specific terms, etc.). Below, we will introduce the steps to create a tag cloud.

Visualization

In the Kibana main screen, we find the option name Visualize, which allows us to create visualizations and aggregations from the indices stored in Elasticsearch. We select to add a new visualization and choose Tag Cloud as the option shown below-

Select Index

The next screen prompts us to select the index to be used in creating the tag cloud. Here, we select count as the type of aggregation index. Then, we select the productname field as the keyword to be used as the tag. Then, we select the index.

After applying the selection, the results displayed here will show a pie chart. Please note the color shadows and values mentioned in the tags.

Tag Cloud Options

Go tooptionsBelow the tag cloud, we can see various configuration options to change the appearance of the tag cloud and the arrangement of the displayed data. In the following example, the tag cloud is displayed with tags distributed horizontally and vertically.
