Card Visualization

Card visualization is the most versatile data visualization Klera offers for visualizing non-aggregated data. It lets you render multimedia data as well as text in a variety of customized formats.

Card visualization represents records as a sequence of cards, hence each card represents a record. Cards are custom designed by the author. The author can design the look, feel, behavior, position, and layout of each field within the card.

The example below demonstrates the analysis of Twitter data with Card visualization.

To create Card visualization:

• Select the desired field(s) and right-click > Select View > Change > Card.

Refer here to learn more about creating a visualization.

The following image shows the resulting Card visualization.

To update the condition for a column:

1. Click on the conditional formatting icon.
2. Change the criterion or format style.
3. Click ‘UPDATE’.

Remove Conditional Formatting

To remove a condition:

To learn more about sorting, refer to the following GIF.

Note: Steps for sorting are the same for Grid and Card visualizations.

Layout Builder

A default layout is created for each card view. The default layout shows all the fields present in the "Columns" section sequentially with column header and column value.

Layout builder lets you visually customize the look and feel of each field of Card. You can configure to render HTML pages, video and audio content as well.

1. Click on the icon for data configuration options.
2. Click on Layout Builder.

In Layout Builder, the list of columns appears on the right side.

You can see the following configuration options with Layout Builder.

1. Add Section

• Fixed Height: The content is shown in a single line. If the content doesn't fit into a single line then ellipsis (...) is shown at the end of the line. You can mouse over to see the complete content in the tooltip.
• Variable Height: The content is shown as a multi-line text with text wrap. Section's height adjusts automatically with content length.

Note: In the default layout, all the sections are of variable height.

 

2. Display

• Value- Content of the field will be displayed.
• Label- Name of the field will be displayed.
• Empty- Empty space will be created.

3. Render As

• Text View: The content is displayed as is with no transformations.
• Reader View- This applies to the URL type content. It fetches the content of the URL from the Internet. It removes all the advertisements, plugins, background images, and other unnecessary content (scripts, etc.) and shows only the readable content to give a clean reading experience for URL type content.
• Link: You can also render URL type content as a hyperlink. When the user clicks on the link it will open the content in a new browser window from the Internet.

4. Font

• You can style labels and value fields by choosing the font style and color.
  

5. Text Alignment

• Left, Right, Center, Justify
• Top Bottom, Middle
