To display a weather map component on a Lightning record page conditionally:

A. Component visibility should be used. This feature in the Lightning App Builder allows components on a Lightning page to be displayed based on specific criteria, such as field values or user attributes. In this case, the app builder can set the visibility of the weather map component to only appear when a house is scheduled for a showing based on the relevant field values.

For more details on setting up conditional component visibility, review the guide on Dynamic Lightning Pages.
