Which Salesforce tool is designed to analyze and visualize donation trends over time?

The tool designed to analyze and visualize donation trends over time is Dashboards. Dashboards provide an interactive platform that allows users to aggregate data from multiple reports into visual components such as charts, graphs, and gauges. This visual representation is crucial for identifying trends, patterns, and overall donation performance over specified periods, making it easier for organizations to assess their fundraising efforts and make informed decisions based on actual data.

In contrast, while reports are essential for generating detailed data sets and can also include visual elements, they are primarily used for data extraction and analysis rather than visualization. Tables, focused on displaying data in a structured format, do not offer the visual analysis capabilities necessary for trend assessment. The Chart Builder is a tool used to create specific charts but does not provide the comprehensive overview and interactive features of a dashboard. Thus, Dashboards are the most effective choice for visualizing and analyzing donation trends over time.
