Which chart type is NOT included in the options offered by Tanium Trends?

The chart types offered by Tanium Trends include various common visualizations that help in displaying data effectively. The bar, donut, and stacked area charts are widely recognized and serve different purposes in data visualization.

Bar charts represent data with rectangular bars, allowing for easy comparison of different categories. Donut charts are a variation of pie charts, used to show proportions and part-to-whole relationships. Stacked area charts help visualize cumulative totals over time while showing different data series stacked on top of each other.

Radar charts, on the other hand, are less common in the context of the visualizations provided by Tanium Trends. They are typically used to display multivariate data in a way that allows users to see how different variables compare across multiple categories simultaneously. This complexity and specific application make radar charts less suited to the general purposes that the other chart types serve within Tanium Trends. Thus, they are not included in the available chart options.
