Mezzobit offers a growing list of visualizations to help customers better understand tag data. The visualizations and many of their options are selected via the data tab control palette:
In most visualizations, each node (circle) is named with the tag name and associated company. In some instances where there isn't an exact match in the Mezzobit database, the domain name and tag object name are instead used. The node color represents the composite index for that tag or company, although this can be changed in the configuration screen.
There are four general options:
- View: There are three views to choose from:
- Chain view shows all tags on a page as a web of parents and children. This provides a view of all tags/companies at one time, although you can zoom in and out to different sections.
- Circle view lists all tags (or companies) along the edge of the circle. By selecting any entry, all parent tags will be highlighted in green and connected by green lines, and the same will occur with red with child tags.
- Tree view lets the user drive through the parent/child tag or company hierarchy one level at a time. Clicking on any node with a number will display the child tags beneath it. Branches many levels deep can be exposed this way, but the visualization will only show a single full branch at any one time due to screen size limitations. In cases where there are more than 10 tags/companies on any level, up and down arrows will enable the user to page through the entire list.
- Nodes: This permits the graph labels and nodes to be toggled between showing tags and showing companies. The company view is much less complex, but a lot of detail is lost. In the future, there will be node options for tag/company categories and functions.
- Labels: By default, all visualizations have labels displayed in auto mode, which chooses how many node labels to display based on the visualization level to avoid overcomplicating the graph and having labels overwrite each other (particularly with large data sets). As you zoom in and the space between nodes increases (as the node size remains constant), more labels are shown. By turning labels off, labels are never shown (as in the example above). With labels turn on, all labels are shown all of the time.
