Final answer:
The tool for a comprehensive visual summary of security-related data is a security dashboard or SIEM system. Measure of America is unrelated, as it deals with socio-economic data.
Step-by-step explanation:
The tool that provides a comprehensive, visual summary of security-related data, including metrics, is known as a security dashboard or a security information and event management (SIEM) system. This kind of tool aggregates and displays data from various sources to help institutions monitor their security status. Although the specific question mentions the Measure of America as a possible reference, it seems to be irrelevant in this context. The Measure of America is an interactive mapping and data tool that provides access to a variety of socio-economic data, not security-related metrics. For visualizing security metrics, other tools designed to manage and analyze security data would be more appropriate.
